Abstract

In this paper, we show an RF-MEMS tunable capacitor that achieves excellent creep immunity and high power-handling capability. The tunable capacitor has a quadruple series capacitor (QSC) structure. The measured result demonstrates +36dBm hot-switching at 85°C with 21V pull-in voltage. The creep immunity is attained by employing SiN spring at the stress concentrations. Compared with aluminum springs, the creep deformation is reduced by a factor of 23 at 100°C.
