Low Cost MillImeter Wave Monolithic Receivers

A 35 GHz receiver using GaAs monolithic and hybrid circuits has been developed for low cost manufacture. The receiver is comprised of a downconverter, an If amplifier and voltage regulators. This paper will report on the design, fabrication, integration, packaging and testing of a monolithic mixer, a monolithic Gunn Diode Oscillator and a GaAs Downconverter circuit which has exhibited a SSB receiver noise figure of 9.5dB.
