  • Abstract
    In this paper, RF MEMS tunable capacitors with low operation voltage, high linearity, high quality factor, and large tuning ratio have been fabricated by utilizing micromachined piezoelectric actuators. The fabricated tunable capacitor has a C/sub max//C/sub min/ ratio of 3.1 to 1 at bias voltages of 6 V and a quality factor of 210 at 1 GHz.
