A 10.5 GHz MIC Direction Sensitive Doppler Module Using a GaAs Fet and a Ag/Pd Thick Film

A MIC direction sensitive doppler module with a GaAs FET oscillator stabilized by a dielectric resonator has been developed by means of a Ag/Pd thick film technique. A module with 17 mW output power at 10.5 GHz has about -90 dBm minimum detectable signal for the bandwidth of 1KHz at the bias condition of 6.5 V, 44 mA.
