Abstract
A power amplifier is described. The power amplifier including at least a first amplifier stage, and at least a first tunable matching network. The first tunable matching network is configured to couple between a first impedance and a second impedance. The first matching network including at least one first set of metal oxide semiconductor variable capacitor arrays.
