Abstract

We present results for ambient temperature and cryogenic operation of mixer receivers for use in the 80-350 GHz range. These systems employ GaAs Schottky barrier diodes doped for optimum performance at 15 K, and make use of a combination of waveguide and quasioptical circuits for LO injection and sideband filtering. Cooled receiver temperatures (DSB) are ~ 65 K at 100 GHz, ~ 250 K at 225 GHz, and -- 530 K at 350 GHz. Local oscillator requirements are < 100 uW in the 3 mm range and 100-300 uW in the 1.5-1 mm range making it feasible to pump these mixers with frequency multiplied sources. The mixer receivers described are tunable over ~ 30-40% of their center frequency. The performance of the frequency multipliers is also discussed. The low noise performance has been achieved in part by use of specially designed FET amplifiers which are cooled to 15 K. For the receivers described, amplifiers centered near 1.5 GHz with ~ 400 MHz bandwidth have been employed.
