This application is based on and claims priority under 35 U.S.C. § 119(e) to a U.S. Provisional Patent Application filed on Feb. 1, 2021 in the United States Patent and Trademark Office and assigned Ser. No. 63/144,222 the contents of which are incorporated herein by reference.
The present disclosure relates generally to multi-band phased-arrays, and more particularly, to tile-based multi-band phased-arrays.
High-speed data transfer between mobile communication devices requires a high-bandwidth communication channel. 5th Generation (5G) cellular technology has extended into the millimeter (mm)-wave frequency band to exploit the wide frequency bands that are available. Phased-array techniques refer to the employment of multiple transmitter/receiver antennas that are spaced at distances proportional to carrier wavelength. These techniques play a pivotal role in sustaining the mm-wave data links. As the high n260 frequency band (37-40 (GHz) and low n257 frequency band (26.5-29.5 GHz) move toward greater commercialization, higher frequency bands (e.g., 47.2-48.2 GHz, 40-43 GHz, and 60 GHz) are also being developed.
Conventionally, phased-arrays employing a radio frequency (RF) phase-shifting architecture are implemented in a single-chip array or in a multi-chip modular phased-array.
The single phased-array chip 102 integrates all front-end (FE) elements 104-1 to 104-n that are required to drive the corresponding antennas. An FE element includes circuits that are repeated for each antenna. Specifically, each FE element includes a low-noise amplifier (LNA) 106, a power amplifier (PA) 108, phase-shifters (PS) 110, and a transmit/receive (T/R) switch 112. During transmission of data stream signals A and B, an on-chip distribution network (or data stream circuitry) 114 having an up/down conversion mixer converts the data stream signals A and B from an intermedia frequency (IF) to a radio frequency (RF) and provides the converted signals to the corresponding FEs 104-1 to 104-n. This architecture is amenable to small form factor solution because all radio elements, such as, for example, clock-generation circuits, calibration circuits, and micro-processors, are integrated onto the same die.
A conventional multi-chip phase-array may also be combined on a printed circuit board (PCB). A unit element on the PCB is a small beam former chip (e.g., a 2×2 or four-element core). Each beam former chip includes a PA, LNA, and PS only. The distribution network (data stream circuitry) and phase-locked loop (PLL) are not included in the beam former chip.
While the architecture on the PCB is more easily scalable than that of
According to one embodiment, a radio frequency integrated circuit (RFIC) is provided. The RFIC includes PLL and data stream circuitry and a plurality of tiles in communication with the PLL and data stream circuitry. The plurality of tiles includes at least one tile for each frequency band of the RFIC. The plurality of tiles are configured to communicate a data stream signal between tiles in a cascading sequence. Each tile of the plurality of tiles includes a plurality of up/down conversion mixers for converting the data stream signal between an IF and an RF. Each tile also includes a plurality of FE elements, each in communication with a corresponding antenna and an up/down conversion mixer of the plurality of up/down conversion mixers.
According to one embodiment, a method is provided for communicating a data stream signal via a RFIC. At least one data stream signal is received at one of a plurality of tiles of the RFIC. The plurality of tiles includes at least one tile for each frequency band of the RFIC. The plurality of tiles are configured to communicate between tiles in a cascading sequence. Each tile of the plurality of tiles includes a plurality of up/down conversion mixers and a plurality of FE elements. Each of the plurality of FE elements is in communication with a corresponding antenna and an up/down mixer of the plurality of up/down mixers. The at least one data stream signal is converted between an IF and an RF at the plurality of up/down conversion mixers of the one of the plurality of tiles.

For example, according to one embodiment, a module may be implemented in a form of an application-specific integrated circuit (ASIC).
Embodiments of the disclosure are directed to a phased-array architecture that supports multiple 5G mm-wave bands with a single phased-array RFIC. Specifically, embodiments provide a single-chip tile-based phased-array architecture. More specifically, a modular architecture is provided in which the phased-array is constructed by cascading tiles. Each band has a dedicated tile design (e.g., vertical tiles) for a multi-band phased-array.
Each tile includes up/down conversion mixers. Accordingly, a signal from each tile is combined at the IF, which is well suited for multi-band designs in which the RF frequency spans almost 24 GHz (e.g., 24.25-48 GHz), Embodiments may also be used with multi-band designs having RF frequency spans with upper limits that exceed 48 GHz.
The tile-based approach allows the signal distribution network (data stream circuitry) to be simplified compared to the conventional architecture of
The single-chip approach allows for integration of FE elements (i.e., those components disposed between the antenna and the mixer), a PLL, a calibration circuit, and a microprocessor within a compact die. Further, the tile-based approach allows for a scalable design in terms of band support.
Each tile includes FE elements and up/down conversion mixers. The tile-based approach uses RF or local oscillator (LO) phase-shifting with IF signal combining, as opposed to the RF phase-shifting and RF signal combining of the conventional architecture. Thus, signal combining is performed at IF, rather than RF. In a multi-band phased-array, the RF signal can extend one octave of bandwidth from 24.5 GHz to 47.5 GHz, Achieving a fiat frequency response over such a large bandwidth results in higher power consumption. In an IF signal combining approach, the signal distribution is at a common IF for all bands, eliminating such power consumption concerns.
For signal transmission via the RFIC, a PLL 202 and signal distribution circuitry (data stream circuitry) accept up to two data streams A and B at the IF (e.g., IF_A 204 and IF_B 206). Data streams A and B may be provided to the RFIC from a center chip in a super-heterodyne architecture. After amplification/buffering while in the IF the data streams A and B are distributed to tiles of the RFIC. Two tiles are provided for each of frequency bands 28, 39, and 47 (e.g., one tile for each data stream) resulting in a total of six tiles. The PLL 202 and signal distribution circuitry are preferably disposed at the center of the RFIC with tiles extending outwardly. Although
IF_A 204 is distributed to first tile 208 of frequency band 28, second tile 210 of frequency band 39, and third tile 212 of frequency band 47. IF_B 204 is distributed to fourth tile 214 of frequency band 28, fifth tile 216 of frequency band 39, and sixth tile 218 of frequency band 47. While this embodiment illustrates six tiles and three specific frequency bands, any number of tiles may be provided representing any frequency band. Further, a single data stream may be provided only to half of the tiles, or the single data stream may be provided to all tiles.
Each tile includes a multiplexer/demultiplexer and two-way splitter/combiner 220 (i.e, 1:2) for distribution of the signal to top and bottom halves of the tile or for passing the signal through to a next adjacent tile in the cascading sequence of tiles. Each tile also includes first and second clock multiplier circuits 222 and 224, and first and second up/down conversion mixers 226 and 228, one of each pair for the top and bottom halves of the tile. The data stream is up-converted from an IF to an RF at the first and second up/down conversion mixers 226 and 228 using a clock frequency signal from the first and second clock multiplier circuits 222 and 124.
The top and bottom halves of the tile also include first and second two-way splitters/combiners 230 and 232 for distribution of the data stream signal to four FE elements. More specifically, the first two-way splitter/combiner 230 splits the data stream signal between first and second FE elements 234 and 236 at a top half of the tile, and the second two-way splitter/combiner 232 splits the data stream signal between third and fourth FE elements 238 and 240 at a bottom half of the tile. An FE element includes circuits that are repeated for each antenna of the tile.
For signal reception via the RFIC, data stream signals are received via the antennas of a tile and processed through the corresponding FE elements 234-240. Top half signals are combined at the first two-way splitter combiner 230, and bottom half signals are combined at the second two-way splitter combiner 232, before the respective combined signals are down-converted at the first and second up/down conversion mixers 226 and 228 using the clock frequency signal from the first and second clock multiplier circuits 222 and 224. Top and bottom half converted signals are combined at the two-way splitter/combiner 220 and through the multiplexer/demultiplexer passing it to the PLL and data stream circuitry, directly or via a previous adjacent tile in the cascading sequence of tiles.
Due to the fact that each tile of the RFIC is cascaded and self-contained without overlap, the tile-based approach relies upon proper signal/clock distribution.
Tiles of different frequency bands of the RFIC operate at different carrier frequencies (FRF,BAND). However, a common intermediate frequency (FIF) for a signal is applied to all of the tiles. Therefore, a clock frequency (FCLK=FRF,BAND−FIF) for up/down-conversion mixers is also different for tiles of different frequency bands. To generate the different clock frequency, a common low-frequency reference clock input (FREF) is distributed across the RFIC. Each tile accepts and buffers the reference clock input (FREF), and sends the reference clock input (FREF) to a next tile in the cascading sequence of tiles. The clock multiplier circuits in each tile generate the clock frequency (FCLK) for the corresponding tile by multiplying the reference clock by a predefined value. A different predefined value may be preset for each tile.
According to an embodiment, one tile in the cascade of tiles on the RFIC is enabled at a time. When one tile is enabled from each of the left and right sides of the circuit, they are required to be for the same frequency band. Without inter-band carrier aggregation, the combiner structure is simplified.
The reference clock input (FREF) is input to first and second clock multiplier circuits 508 and 510 in the top and bottom halves of the tile 502, and also output, via a through channel, from an opposite end of the tile 502 to a next tile in the cascading sequence of tiles. The reference clock input (FREF) is provided to each tile of the RFIC. The first and second clock multiplier circuits 508 and 510 buffer the reference clock input (FREF) and multiply the reference clock input (FREF) by a predefined value N resulting in a clock frequency (FCLK). Tiles are preset with different predefined values N to result in the proper clock frequency (FCLK) for a given tile.
When the RFIC corresponds to an active channel during transmission, the first and second clock multiplier circuits 508 and 510 provide the clock frequency (FCLK) to corresponding first and second up/down conversion mixers 512 and 514, one in each of the top and bottom halves of the tile 502. The first and second up/down conversion mixers 512 and 514 are also provided with the data stream signal from the two-way splitter/combiner 506. Using the clock frequency (FCLK), the first and second up/down conversion mixers 512 and 514 up-convert the data stream signal from an IF to an RF operating at a carrier frequency (FRF,BAND). The first up/down conversion mixer 512 provides the up-converted data stream signal to a first two-way splitter/combiner 516 that splits the data stream signal between first and second FE elements 520 and 522 of the tile 502. Similarly, the second up/down conversion mixer 514 provides the up-converted data stream signal to a second two-way splitter/combiner 518 that splits the data stream signal between third and fourth FE elements 524 and 526.
Each of the FE elements 520-526 includes a PS 528, an LNA 530, a PA 532, and a T/R switch 534. When the RFIC corresponds to an active channel during transmission, the data stream signal is provided through the PS 528, the PA 532, and the T/R switch 534 of each FE element, before being transmitted at the RF via a corresponding antenna. When the PS 528 is an RF PS, the tile uses a two up/down conversion mixers. When the PS 528 is an LO PS, the tile uses four up/down conversion mixers.
When the RFIC is utilized for reception of a data stream signal at the RF through the antennas of the tile 502 (e.g, the tile 502 corresponds to an active channel), the signal is provided through the T/R switch 534, the LNA 530, and the PS 528 of the FE elements 520-526. Data stream signals from the first and second FE elements 520 and 522 are combined at the first two-way splitter/combiner 516. Data stream signals from the third and fourth FE elements 524 and 526 are combined at the second two-way splitter/combiner 518. Combined data stream signals are provided from the first and second two-way splitter combiners 516 and 518 to the first and second up/down conversion mixers 512 and 514, which down-convert the data stream signals from the RF to the IF using the clock frequency (FCLK) from the first and second clock multiplier circuits 508 and 510, respectively. The down-converted signals are provided from the first and second up/down conversion mixers 512 and 514 to the two-way splitter/combiner 506, which combines the down-converted signals. The multiplexer/demultiplexer 504, acts as a multiplexer and receives the combined signal from the two-way splitter/combiner 506, and outputs the combined signal from the tile 502. The signal is output from the tile 502 to a PLL and data stream circuitry of the RFIC, either directly or via one or more previous tiles in the cascading sequence of tiles in the RFIC.
When the RFIC is utilized for reception, but the tile 502 corresponds to an inactive channel, the multiplexer 504 receives a signal from a subsequent tile in the cascading sequence, and the multiplexer 504 passes this signal through to the PLL and data stream circuitry of the RFIC, either directly or via one or more previous tiles in the cascading sequence of tiles in the RFIC.
When the RFIC is transmitting a data stream signal, the reference clock input (FREF) and the data stream signal are provided in a cascading fashion from tile to tile. Specifically, the reference clock input (FREF) is cascaded through each of the first through third tiles 602-606, while the data stream signal cascades through the tiles corresponding to inactive channels until a tile corresponding to an active channel is reached.
When the RFIC is receiving a data stream signal, the reference clock input (FREF) is provided in the same cascading fashion from tile to tile. When the data stream signal is received through the antennas of the third tile 606, the signal is output from the third tile 606 and cascaded in a reverse direction through the second tile 604 and the first tile 602 before reaching the PLL and data stream circuitry of the RFIC. When the data stream signal is received through the antennas of the second tile 604, the signal is output from the second tile 604 and cascaded in a reverse direction through the first tile 602 before reaching the PLL and data stream circuity of the RFIC. When the data stream signal is received through the antennas of the first tile 602, the signal is output from the first tile 602 to the PLL and data stream circuitry of the RFIC.
Each tile is has a different predefined value N1, N2, N3, for use in their respective clock multiplier circuits. Accordingly, each tile may have a different clock frequency (FCLK) and operates at a different carrier frequency (FRF,BAND).

The one or more instructions may include code generated by a complier or code executable by an interpreter. A machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term “non-transitory” indicates that the storage medium is a tangible device, and does not include a signal (e.g., an electromagnetic wave), but this term does not differentiate between where data is semi-permanently stored in the storage medium and where the data is temporarily stored in the storage medium.
According to one embodiment, a method of the disclosure may be included and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read only memory (CD-ROM)), or be distributed (e.g., downloaded or uploaded) online via an application store (e.g., Play Store™), or between two user devices (e.g., smart phones) directly. If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in the machine-readable storage medium, such as memory of the manufacturer's server, a server of the application store, or a relay server.
According to one embodiment, each component (e.g., a module or a program) of the above-described components may include a single entity or multiple entities. One or more of the above-described components may be omitted, or one or more other components may be added. Alternatively or additionally, a plurality of components (e.g., modules or programs) may be integrated into a single component. In this case, the integrated component may still perform one or more functions of each of the plurality of components in the same or similar manner as they are performed by a corresponding one of the plurality of components before the integration. Operations performed by the module, the program, or another component may be carried out sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be executed in a different order or omitted, or one or more other operations may be added.
Although certain embodiments of the present disclosure have been described in the detailed description of the present disclosure, the present disclosure may be modified in various forms without departing from the scope of the present disclosure. Thus, the scope of the present disclosure shall not be determined merely based on the described embodiments, but rather determined based on the accompanying claims and equivalents thereto.
