Abstract
For use in a wireless network, a tunable power amplifier circuit includes a power amplifier transistor and a plurality of laminate MEMS (microelectromechanical system) capacitors coupled to the power amplifier transistor. The laminate MEMS capacitors are arranged in a tunable matching network and configured to provide a matching impedance for the power amplifier transistor. In some embodiments, the laminate MEMS capacitors are arranged in a binary array.
