Abstract

A quasi-optical millimeter-wave (MMW) monolithic monopulse receiver and its performance when integrated with a quasi-optical diplexer and antenna are described. The integration of the antenna, diplexer, and receiver forms a complete MMW radar front end. The receiver, which is fabricated on 0.25-in thick GaAs substrates, includes four monolithic chips. The entire receiver is packaged on the planar back surface of a 1.5-in-diameter lens. This lens, hyperhemispherical in shape, provides a dual function as a focussing lens and carrier for the monolithic receiver. Measured noise figure and conversion gain of the receiver are 8.7 dB and 19.0 dB, respectively, at 35.0 GHz.
