Abstract

A high-performance 6-18-GHz dual-channel monolithic microwave integrated circuit (MMIC) transmit/receive (T/R) module is presented with significant advances in integration and performance. This advanced module featured critical spacing for two-dimensional arrays, an aluminum silicon carbide housing, multilayer ceramic substrates for RF and control circuitry, a custom hermetic DC multipin connector, new high-performance MMIC low-noise amplifiers and power amplifiers, and specialized multifunction MMIC chips for a reduced parts count. Each of the two channels featured a selectable horizontal and vertical polarization capability. The module was very densely packaged with two complete T/R channels occupying 0.97 in/sup 3/. The module´s nominal noise figure was below 8.0 dB over most of the band, the output power was 26 dBm, and both the measured transmit and receive gains were 20 dB.<>
