Claims
- 1. A mixer circuit, comprising:
- a differential amplifier comprising a pair of transistors, each transistor of said pair of transistors comprising a collector;
- a double balanced mixer comprising a first pair of transistors and a second pair of transistors, each transistor of said first and second pairs of transistors comprising an emitter;
- a first impedance element interposed between a junction between the emitters of said first pair of transistors of said double balanced mixer and the collector of one of said pair of transistors of said differential amplifier; and
- a second impedance element interposed between a junction between the emitters of said second pair of transistors of said double balanced mixer and the collector of the other of said pair of transistors of said differential amplifier.
- 2. A mixer circuit according to claim 1, wherein each of said first and second impedance elements is a resistor.
