Abstract

A W-band source module providing 4-GHz tuning bandwidth (92.5-96.5 GHz) has been developed. This module consists of three MMIC chips fabricated in TRW production lines, which are a 23.5 GHz HBT VCO, a 23.5 to 94 GHz HEMT frequency quadrupler and a W-band three-stage HEMT output amplifier. It exhibits a measured peak output power of 3 dBm at 94-95 GHz and a 3-dB tuning bandwidth greater than 3 GHz, with a phase noise of -90 dBc/Hz at 1 MHz offset. This work demonstrates a new and efficient way to implement high performance W-band source. Its wide tuning bandwidth with good phase noise performance, as well as design simplicity, makes this approach attractive for many W-band system applications.<>
