Abstract
An apparatus and method for a switched capacitor architecture for multi-band Doherty power amplifiers are provided. The apparatus is for amplifying Radio Frequency (RF) signals, and the apparatus includes a multi-band Power Amplifier (PA) including a plurality of input matching circuits including switchable capacitors, and a plurality of output matching circuits including the switchable capacitors, wherein the multi-band PA is tunable to more than one RF frequency band.
