A Mixer and Solid State L.O. for a 60 GHz Receiver

This paper describes the techniques evolved and the results obtained during the development of solid state RF component for use in the 50-70 GHz frequency range. The program is directed specifically toward the generation of a reliable, low noise, RF "front-end" for a 60 GHz radiometric receiver. The critical. components of the "front -end" are the low noise (low conversion loss ) mixer and the local oscillator. The mixer consists of GaAs Schottky barrier diodes of very high cut-off frequency; the local oscillator utilizes a silicon avalanche diode oscillator.
