Abstract :
It is very desirable to have tunable or reconfigurable RF front-end and devices for the modern wireless mobile phones since they need to operate over multiple bands, ranging from 700 MHz to 2700 MHz. The role of MEMS tunable capacitors with high Q factors is crucial in the tunable RF front-end for the modern mobile phones. In this paper, we will show the attractive performance of MEMS tunable capacitors in some important applications such as impedance matching, tunable filters, and tunable mobile antennas.
