Description

TECHNICAL FIELD

The present disclosure relates to an adaptable microwave radio transceiver system comprising a microwave radio transceiver that is adapted for at least two waveguide frequency bands and comprises at least one radio port.

BACKGROUND

In many fields of wireless communication, such as microwave communication, as well as for applications associated with radars and other sensors using microwave technology, waveguides are used for transporting wireless signals, due to the low losses incurred in a waveguide.

A waveguide transition is usually needed when a waveguide interface, for example an antenna feeder, is mounted to a radio unit, where the transition is integrated in the microwave radio transceiver and comprises a shorted waveguide part with a probe. Previously, the bandwidth of waveguides and waveguide transitions has not limited the bandwidth of the microwave radio transceiver since the bandwidth of microwave radio components have been limited relative the bandwidth of the waveguide.

Today, microwave radio components have an increased wideband performance, and therefore the bandwidth of the waveguide will limit the useable bandwidth, and not as before the microwave radio components. Due to the limits of the waveguide, there will be a higher complexity in production regarding different frequency bands, different test stations, different mechanics etc.

Even if the microwave radio transceiver is capable of handling all frequency bands used, the waveguide transition will only be able to handle specific frequency bands, and therefore different microwave radio transceiver with different waveguide transitions that are adapted for the current waveguide band have to be made.

There is thus a need for an adaptable microwave radio transceiver system with corresponding components that can handle the different frequency bands comprised in the frequency band that the radio unit handles.

SUMMARY

It is an object of the present disclosure to provide an adaptable microwave radio transceiver system with corresponding components, where the system that can handle the frequency band of the radio unit. It is also an object of the present disclosure to provide a corresponding microwave radio transceiver and microwave waveguide adapter.

Said object is obtained by means of an adaptable microwave radio transceiver system comprising a microwave radio transceiver and at least two waveguide adapters, where the microwave radio transceiver is adapted for at least two waveguide frequency bands and comprises at least one radio port. Each radio port comprises a corresponding probe of a fixed length that is connected to a radio part, and extends via an inner insulating part in a bottom comprised in the corresponding radio port. Each waveguide adapter comprises a first end that is adapted to face the corresponding bottom, where each first end comprises a bottom wall with an outer insulating part, through which outer insulating part the corresponding probe is adapted to protrude a protrusion distance when mounted. The protrusion distance is dependent on a thickness of the bottom wall, where at least two waveguide adapters have different thickness of the corresponding bottom wall. Any one of the waveguide adapters is exchangeably mountable to said radio port.

In this way, the same type of radio transceiver can be adapted to handle different frequency bands, where different separately available waveguide adapters are sued to adapt the radio transceiver to a desired frequency band.

According to some aspects, each radio port comprises a corresponding radio cavity that in turn comprises the probe and has said bottom and a top. For each radio cavity, the probe extends within the radio cavity via the inner insulating part in the bottom towards the top. Each radio cavity is adapted to receive a corresponding waveguide adapter that comprises an adapter cavity that is adapted to be inserted into the radio cavity. The corresponding probe is adapted to protrude a protrusion distance within the corresponding adapter cavity when mounted.

In this way, a secure and reliable mounting is provided.

According to some aspects, at least one radio cavity and at least one corresponding adapter cavity has a square shape.

In this way, orthogonal polarizations can be handled.

According to some aspects, each waveguide adapter comprises a first adapter port and a second adapter port, where the first adapter port comprises a first adapter cavity and the second adapter port comprises a second adapter cavity, where the adapter cavities are connected via a diplexer arrangement comprised in the waveguide adapter.

In this way, a diplexer arrangement can comprise suitable adapter ports such that it can be mounted to any radio transceiver comprising corresponding radio ports.

DETAILED DESCRIPTION

Aspects of the present disclosure will now be described more fully hereinafter with reference to the accompanying drawings. The different devices, systems, computer programs and methods disclosed herein can, however, be realized in many different forms and should not be construed as being limited to the aspects set forth herein. Like numbers in the drawings refer to like elements throughout.

The terminology used herein is for describing aspects of the disclosure only and is not intended to limit the invention. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

With reference to FIG. 1 and FIG. 2, showing a first example, there is microwave radio transceiver 14 comprising one radio port 20. that in turn comprises a corresponding radio cavity 2 with a probe 3 of a fixed length that is connected to a radio part 4. The radio cavity has a bottom 5 and a top 6, where the probe 3 extends within the radio cavity 2 via an inner insulating part 7 in the bottom 5 towards the top 6. According to some aspects, the inner insulating part 7 is formed in a plastic material such as for example polytetrafluoroethylene (PTFE).

With reference also to FIG. 3-7, the radio cavity 2 is adapted to receive a corresponding waveguide adapter 8₁, 8₂. Here, two different waveguide adapters 8₁, 8₂ are shown, and the adaptable microwave radio transceiver system 1 can comprise any number of different waveguide adapters 8₁, 8₂ that together can provide coverage for all frequency bands the radio part 4 is capable of handling. Therefore, one standard microwave radio transceiver 14 can be made for all frequency bands the radio part 4 is capable of handling, having an identical radio cavity 2. Adaption for the waveguide part 14 that is to be used is acquired by mounting the correct waveguide adapters 8₁, 8₂.

According to the first example, each waveguide adapter 8₁, 8₂ comprises an adapter port 21₁, 21₂ with an adapter cavity 9 that is adapted to be inserted into the radio cavity 2. FIG. 3 shows a top view of a microwave radio transceiver 14 and two waveguide adapters 8₁, 8₂. FIG. 4 shows a first section view of FIG. 3 where a first waveguide adapter 8₁ is about to be mounted to the radio cavity 2, and a second waveguide adapter 8₂ is standing by, not being used at the moment. FIG. 6 shows a second section view of FIG. 3 where the first waveguide adapter 8₁ has been mounted to the radio cavity 2. FIG. 5 shows an enlarged cut-open side view of the first waveguide adapter 8₁ that is about to be mounted to the radio cavity 2, and FIG. 7 shows an enlarged cut-open side view of the first waveguide adapter 8₁ when it has been mounted to the radio cavity 2.

Each waveguide adapter 8₁, 8₂ comprises a first end 15 and a second end 10 that is opposite the first end 15, where the first end 15 is adapted to face the bottom 5 and comprises a bottom wall 12₁, 12₂ with an outer insulating part 13. The probe 3 is adapted to protrude through the outer insulating part 13 and extend a protrusion distance D within the adapter cavity 9 when mounted. It is to be noted that the protrusion distance D is dependent on a thickness T₁, T₂ of the bottom wall 12₁, 12₂.

The second end 10 comprises a waveguide interface 11₁, 11₂ and is adapted to face a waveguide part 17, for example in the form of an antenna feeder 17 that is comprised in an antenna arrangement 18 as shown in FIG. 8. In this way, by choosing a waveguide adapter 8₁, 8₂ with an adapted protrusion distance D, it is possible to acquire a tuning to a desired frequency band for the waveguide interface 11₁, 11₂ and the waveguide part 17. This is illustrated in FIG. 3, FIG. 4 and FIG. 6 where there is an adaptable microwave radio transceiver system 1 comprising the microwave radio transceiver 14 and two waveguide adapters 8₁, 8₂. The protrusion distance D for the respective waveguide adapter 8₁, 8₂ is dependent on the thickness T₁, T₂ of the respective bottom wall 12₁, 12₂. Since the waveguide adapters 8₁, 8₂ have different thickness T₁, T₂ of the corresponding bottom wall 12₁, 12₂, they provide different protrusion distance D and therefore offer tuning to different frequency bands for the waveguide interface 11₁, 11₂ and the waveguide part 17. Any one of the waveguide adapters 8₁, 8₂ is exchangeably mountable to the radio port.

With reference to FIG. 4, the thicknesses T₁, T₂ of the bottom walls 12₁, 12₂ and the size of the waveguide interfaces 11₁, 11₂ indicate that the first waveguide adapter 8₁ is adapted for a lower frequency band than the second waveguide adapter 8₂, the thickness T₁ being smaller and the waveguide interface 11₂ being larger for the first waveguide adapter 8₁.

Depending on function and requirement, a microwave radio transceiver 14 can comprise more than the one radio cavity 2 shown. According to some aspects, with reference to FIG. 9, showing a second example, the microwave radio transceiver 14′ comprises a transmitting radio port 20a adapted to transmit a generated signal, and a receiving radio port 20b adapted to receive a received signal. The transmitting radio port 20a comprises a first radio cavity 2a, a first inner insulating part 7a, and a first probe 3a. The receiving radio port 20b comprises a second radio cavity 2ba, a second inner insulating part 7b, and a second probe 3b.

With reference to also to FIG. 10 that shows a waveguide adapter 8′ according to the second example mounted to the radio ports 20a, 20b and FIG. 11 that shows a section of FIG. 10, the waveguide adapter 8′ comprises a first adapter port 21a and a second adapter port 21b. The first adapter port 21a comprises a first adapter cavity 9a and a first outer insulating part 13a, and the second adapter port 21b comprises a second adapter cavity 9b and a second outer insulating part 13b, where the adapter cavities 9a, 9b are connected via a diplexer arrangement 19 comprised in the waveguide adapter 8′. The first adapter cavity 9a is adapted to be mounted to the first radio cavity 2a and the second adapter cavity 9b is adapted to be mounted to the second radio cavity 2b. In this way, a diplexer arrangement 19 is integrated in the waveguide adapter 8′ and is adapted to be connected to corresponding ports 20a, 20b in the microwave radio transceiver 14.

The diplexer arrangement comprises a waveguide interface 11′ corresponding to the one described previously, and the probes 3a, 3b are connected to a radio part 4′.

This means that one and the same microwave radio transceiver 14′ can be used to be connected to different diplexer arrangements 19, where the microwave radio transceiver 14′ comprises a transmitting radio port 20a and a receiving radio port 20b. There can be a number of diplexer arrangements 19 that together provide functionality for the frequency bands the radio part 4 is capable of handling. Therefore, one standard microwave radio transceiver 14 can be made for all frequency bands the radio part 4 is capable of handling, having identical radio cavities 2a, 2b.

According to some aspects, at least one radio cavity 2; 2a, 2b and at least one corresponding adapter cavity 9; 9a, 9b has a square shape. This enables an adapter cavity 9; 9a, 9b to be mounted to a radio cavity 2; 2a, 2b in different steps of 90°, allowing for adaptation to orthogonal polarizations.

By means of the present disclosure, in order to compensate for the inherent limitation in bandwidth of waveguides, an adaptive coaxial interface is disclosed. A waveguide transition is formed with a coaxial probe having a protrusion distance D that is used to set transition performance, where a smaller protrusion distance D corresponds to a higher frequency.

By means of the present disclosure, wide band microwave radio transceivers that can support more than one waveguide band are enabled, which confers a big advantage in production. The customers will benefit from universal spare parts, as one spare part could replace any frequency in their network. For microwave radio transceivers with diplexers, logistics will be alleviated as the customer can change to their preferred index/version in field.

The present disclosure can of course be applied to many different situations and applications. As shown in FIG. 12, the waveguide adapter 8″ comprises a third adapter port 21c and a fourth adapter port 21d, where the third comprises a third adapter cavity 9c and the fourth adapter port 21d comprises a fourth adapter cavity 9d, where the adapter cavities 9c, 9d are connected via a power loop waveguide section 22. In this manner, the transmitting radio port 20a and the receiving radio port 20b can be connected and radio functionality be tested when the third adapter port 21c and the fourth adapter port 21d are connected to the corresponding radio ports 20a, 20b in the microwave radio transceiver 14′.

As shown in FIG. 12, this waveguide adapter 8″ also comprises the previously described diplexer arrangement 19, and depending on how the waveguide adapter 8″ is turned either the diplexer arrangement 19 or the power loop waveguide section 22 is connected to the transmitting radio port 20a and the receiving radio port 20b since, on the one hand, the first adapter port 21a and the second adapter port 21b, and on the other hand, the third adapter port 21c and the fourth adapter port 21d are positioned on opposite sides. A separate waveguide adapter only comprising the third adapter port 21c, the fourth adapter port 21d and the power loop waveguide section 22 is of course also conceivable.

Yet another alternative is disclose in FIG. 13, where the microwave radio transceiver 14″′ comprises a separate transmitting test radio port 20c adapted to transmit a generated signal, and a separate receiving test radio port 20d adapted to receive and detect a signal that is transferred from the transmitting test radio port 20c. Here, there is a waveguide adapter 8″′ that comprises the previously described diplexer arrangement 19 and power loop waveguide section 22, and since the first adapter port 21a, the second adapter port 21b, the third adapter port 21c and the fourth adapter port 21d are positioned on the same side, these ports can be connected to the radio ports 20a, 20b, 20c, 20d of the microwave radio transceiver 14″′ simultaneously, such that the microwave radio transceiver 14″′ can be operated and tested at the same time.

With reference to FIG. 16, the present disclosure relates to a method for configuring a microwave radio transceiver system 1; 1a, 1b comprising at least two waveguide adapters 8₁, 8₂; 8′ and a microwave radio transceiver 14 adapted for at least two waveguide frequency bands.

For each waveguide adapter 8, 8′, the method comprises providing S300 at least one corresponding adapter cavity 9; 9a, 9b that is adapted to be inserted into a corresponding radio cavity 2, 2a, 2b, each waveguide adapter 8₁, 8₂, 8′ comprising a first end 15 that is adapted to face the corresponding bottom 5. For each adapter cavity 9; 9a, 9b in a waveguide adapter 8₁, 8₂, 8′, the method comprises providing S400 a bottom wall 12₁, 12₂ with an outer insulating part 13 at the first end 15, through which outer insulating part 13 the corresponding probe 3 is adapted to protrude a protrusion distance D within the adapter cavity 9; 9a, 9b when mounted. The protrusion distance D is dependent on a thickness T₁, T₂ of the bottom wall 12₁, 12₂, where at least two waveguide adapters 8₁, 8₂, 8′ have different thickness T₁, T₂ of the corresponding bottom wall 12₁, 12₂, where any one of the waveguide adapters 8₁, 8₂, 8′ is exchangeably mountable to said radio port 20; 20a, 20b.

According to some aspects, the method comprises choosing S500 a waveguide adapter 8₁, 8₂ among the available waveguide adapters 8₁, 8₂, where the chosen waveguide adapter 8₁, 8₂ is adapted for a chosen waveguide frequency band; and mounting S600 the chosen waveguide adapter 8₁, 8₂ to a corresponding radio port 20; 20a, 20b.

The present disclosure is not limited to the above, but may vary freely within the scope of the dependent claims. For example, a radio cavity and a corresponding adapter cavity can have any suitable shape such as circular, oval, octagonal etc.

According to some aspects, with reference to FIG. 14 that corresponds to FIG. 7 and shows an alternative radio port 20_X, each waveguide adapter 8₁ can be mounted in a countersink at the microwave radio transceiver 14 such that the waveguide adapter 8₁ becomes more or less flush with the outer surface of the microwave radio transceiver 14 at the place of mounting.

According to some aspects, with reference to FIG. 15 that corresponds to FIG. 7 and shows an alternative radio port 20_Y, there need not be any radio cavity comprised in the radio port. The radio port 20_Y can instead comprise a bottom 5 that is more or less flush with the outer surface of the microwave radio transceiver 14 as indicated in FIG. 15, or even protrude from the outer surface of the microwave radio transceiver 14. Different shapes are also possible such as concave-convex and similar. According to some further aspects, in particular for this case, there can be guiding pins 23a, 23b and corresponding guiding apertures 24b, 24b (only two shown in FIG. 15 for reasons of clarity, but there can of course be more guiding pins and guiding apertures provided at each waveguide adapter 8₁ and the radio port 20_Y in a well-known manner and similar that ensure that the waveguide adapter 8₁ is mounted correctly.
