Abstract

This paper presents an X-band tunable voltage controlled oscillator (VCO) using WIN™ 0.25 μ mGaN process. The power VCO was implemented by a class E power amplifier with positive feedback to generate an output power of 27.89 dBm at 9.4 GHz. The total power consumption is 2204 mW. The DC-to-RF conversion efficiency is 27.S9%. A source-drain connected GaN transistor was used as a varactor which provided the tuning frequencies from 9.348 to 9.46 GHz. The best measured phase noise is-121.62dBc/Hz at 1-MHz offset frequency. The FoMp and FoMposc are-195.49 and-223.38, respectively. The chip size includes all pads is 2× 1.5mm2.
