Abstract

A power amplifier has at least a first amplifier circuit with an output port and at least a second amplifier circuit with an output port. The power amplifier further has at least a coupler with a first and a second input port and a first and a second output port. The first input port of the coupler is coupled with the output port of the first amplifier circuit and the second input port of the coupler is coupled with the output port of the second amplifier circuits. The power amplifier further has a switch with at least an input terminal and at least two output terminals. The input terminal of the switch is coupled with the first output port of the coupler, wherein each of the output terminals of the switch is connected with a respective terminal impedance, the terminal impedances having different impedance values.
