Abstract
The systems and methods described herein provide for a radio frequency micro-electromechanical systems switch having two or more resonant frequencies. The switch can be configured as a capacitive shunt switch having a deflectable member coupled between two electrodes over a transmission line. A first insulator can be located between one of the electrodes and the deflectable member to form a capacitive element. The deflectable member can be deflectable between an up-state and a down-state, the down-state capacitively coupling the deflectable member with the transmission line. The degree by which the deflectable member overlaps the first insulator can be adjusted to adjust the capacitance of the capacitive element and the resulting resonant frequency.
