Abstract :
This paper describes the development of novel GaAs MMICs which are to be used to implement a planar array of single-sideband, ultra-low-noise receivers. The receivers may be adjusted to operate at any frequency between 80 and 110 GHz, with image rejection greater than 15 dB, by tuning the local oscillator. The MMICs have been designed to perform well when cryogenically cooled to below 20 K
