Abstract
A circuit for dynamically combining/splitting power amplifier outputs having at least four power input ports. The input ports are joined by a 360 degree transmission line having three switches spaced 90 degrees apart. Two coupled line circuits are connected to the transmission line. The coupled line circuits are placed in parallel and each of the coupled line circuits selectively provides either 50 Ohms or 70.7 Ohms impedance.
