Abstract
A monolithic V-band VCO using M-based HBT technology has been designed , fabricated, and tested. This VCO delivers a peak output power of 4 d Bm at a center frequency of 62.4 GHz with a tuning range of 300 MHz. T he measured phase noise shows -78 dBc/Hz at 100 kHz offset and -104 dB c/Hz at 1 MHz offset. To our knowledge, this is the highest frequency fundamental-mode oscillator ever reported using bipolar transistors.
