Abstract

A W-band voltage control oscillator (VCO) using 0.1m AlGaAs/InGaAs/GaAs PHEMT MMIC technology with ultra low phase noise is presented. This VCO demonstrated an operation frequency centered at 97 GHz with a tuning range of 2GHz and an output power of 1 mW. The measured single side-band phase noise is-88 dBc/Hz at 1 MHz offset. To the best of our knowledge, this phase noise performance is not only the best among the previously reported results for HEMT MMIC VCO at this frequency, but also rivals those for most VCOs using HBTs.
