Novel 900 MHz/1.9 GHz dual-mode power amplifier employing MEMS switches for optimum matching

A novel scheme is proposed for a compact band-switchable power amplifier that employs Micro-Electro-Mechanical System (MEMS) switches in a matching network (MN). According to the on/off status, the switches change the frequency response of the MN, and then the optimum matching can be achieved in dif...
