This paper details the design, realisation and measured performance of a set of MMICs for broadband receiver applications. Five different MMICs are described: A 0.5 to 20GHz dual channel limiter, a 2 to 18GHz dual channel Low Noise Amplifier (LNA), a DC to 20GHz dual channel Single Pole Double Throw (SPDT) switch, a 2 to 18GHz upconverter and a companion downconverter. The MMICs can be used to implement a compact, dual channel 2-18GHz receiver and an example of this is also described.
