MIC Assembly for 12-GHz Direct Broadcast Satellite Receiver

This paper describes the MIC assembly for 12-GHz direct broadcast satellite(DBS) earth-station receivers. It is a compact assembly consisting of a GaAsFET amplifier, an image rejection filter, a diode mixer, a dielectric resonator oscillator and an IF amplifier. A DBS receiver incorporating this unit achieves an overall noise figure <3.0dB for frequencies from 11.7 to 12.2GHz.
