An all GaAs MMIC wideband 6 to 4 GHz downconverter technology demonstrator has been designed, developed, fabricated and tested. The module achieves an overall conversion gain of 67 dB with a 3.2 dB noise figure. The MMIC chip set developed includes an LNA, an active splitter, phase shifters, a mixer, broadband power combiners and an IF amplifier. The assembly represents a significant size and weight reduction compared to conventional hybrid units.

A multipurpose, 0, 04 - 4 GHz, monolithic GaAs detector circuit has been fabricated. It shows a sensitivity of 2.5 V/rad with a DC offset of 300 mV for a differential dynamic range of 8V. It has been successfully tested as a phase detector in a homodyne receiver over L and S bands.
