Abstract
In this paper, we report state-of-the-art high frequency performance of a W-band voltage-controlled oscillator (VCO) MMIC realized in a 0.1 µm AlGaN/GaN HEMT technology. The oscillation frequency of the VCO can be tuned between 85.6 and 92.7 GHz, which is a relative tuning bandwidth of 8 %. The achieved maximum output power is as high as 10.6 dBm. The phase noise of the VCO varies from -80.2 to -90.2 dBc/Hz at 1 MHz offset from the carrier over the tuning voltage range.
