Abstract
The disclosure is directed to microelectromechanical system (MEMS) switches with multiple pull-down electrodes between terminal electrodes to limit off-state capacitance. In exemplary aspects disclosed herein, a plurality of pull-down electrodes are positioned between the input terminal electrode and the output terminal electrode. The plurality of pull-down electrodes are offset from each other to limit off-state capacitance between the input terminal electrode and the output terminal electrode. The separation between the pull-down electrodes disrupts the off-state capacitive path between the input terminal electrode and the output terminal electrode, thereby further insulating the contacts from each other. Limiting off-state capacitance reduces on-state electrical loss and increases off-state electrical isolation for improved performance.
