Abstract :
In this paper, we demonstrate the critical design considerations for GaN-based microwave power varactors for the purpose of achieving high breakdown voltage, high Q-factor and high linearity. The extraction of these parameters from a real GaN-based power varactor diode is also presented. High values of these parameters are obtained, which is critical for the applications in the wireless base-station communications.
