Abstract
A power amplifier circuit includes a power amplifier responsive to a power mode signal, the power amplifier having a power amplifier output node, and a power amplifier load circuit also responsive to the power mode signal, the power amplifier load circuit having a load circuit input node connected to the power amplifier output node. The power amplifier load circuit has a first transmission line coupled between the load circuit input node and a first node, a harmonic filter coupled between the load circuit input node and a common node, a first capacitor coupled between the first node and the common node, and a first switch coupled between the common node and ground, where the first switch is responsive to the power mode signal.
