An ultra low phase noise 89-GHz frequency source module based on MMIC technology is developed. This source module consists of a 5.5625-GHz fundamental-mode dielectric resonator oscillator and a diode doubler using GaAs-based HBT MMIC technology, a 11--to-22 GHz doubler, a 22-to-88 GHz quadrupler, and W-based output amplifiers fabricated using GaAs HEMT MMIC technology. The module is packaged in a miniature and hermetically sealed housing, and has good phase noise performance due to the low 1/f noise of the GaAs-based HBT devices and the high-Q off-chip dielectric resonator. At 89 GHz, the measured phase noise results are - 112 and -125 dBc/Hz and 1-kHz and 1-MHz offset, respectively. These results represent state-of-the-art performance for the MMIC based W-band source module.
