Abstract
An RF MEMS capacitor design, fabrication and measurement is described. The capacitor's dual gap height architecture allows for continuous electrostatic tuning with low resistive loss and a large tuning range. Two voltage sources are used to reach the full tuning potential of the device. Measurements indicate a capacitance tuning range of 6.2:1 with a quality factor over 50 at 30 GHz for 310 fF.
