A fundamental low phase noise W-band VCO extended by an output buffer using InP/InGaAs DHBT technology is reported. The fully integrated differential VCO exhibits operation frequencies ranging from 83 to 89 GHz. At 87 GHz, a minimum phase noise of -102 dBc/Hz at 1 MHz offset frequency has been achieved. Within the tuning range, a single ended output power up to 5 dBm was measured, resulting in a total signal power of 8 dBm.
