Pi-shaped MEMS architecture for lowering actuation voltage of RF switching
Mafinejad, Yasser, Kouzani, Abbas Z., Mafinezhad, Khalil and Golmakani, Abbas 2009, Pi-shaped MEMS architecture for lowering actuation voltage of RF switching, IEICE electronics express, vol. 6, no. 20, pp. 1483-1489.
A wide band low actuation capacitive coupling electrostatic RF MEMS switching device is presented in this paper. The device includes a pi-shaped matching architecture containing two switches connected by a high impedance short transmission line. The device can act as a switch for any desired frequency whilst requiring only 12volts for actuation. By optimizing the length and the characteristic impedance of the transmission line, the switch can be tailored for desired frequency bands. The switch is calculated and simulated for Ka to V frequency bands demonstrating excellent improvements of RF characteristics.
