  • Non-switching adaptable 4-way power splitter/combiner
    Patent number: 7005942
    Abstract: A 4-way power splitter/combiner circuit providing a plurality of transmission lines of selected impedance and phase shift to define four amplifier ports into which one to four amplifiers may be populated without reconfiguration of the circuit. The circuit provides acceptable VSWR and return loss under each operating condition.

  • Dynamic combiner/splitter for RF signal systems
    Patent number: 6650200
    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.
