Abstract
A receiver for use at 225 GHz has been designed and built. It uses a low noise, subharmonically pumped, balanced mixer that requires a local oscillator (LO) at only one fourth the signal frequency. The local oscillator is a commercially available 56 GHz phase locked Gunn oscillator with a 50 mW power output. Preliminary results indicate a 12 dB system noise figure (DSB).
