  • Patent number: 8508313
    Abstract: Devices are described that combine or divide electromagnetic signal power using short-circuited parallel-coupled multiconductor transmission lines. Such devices include single-stage, multi-stage ‘traveling wave’, and multi-stage broadband filter structures. Electrically shorting each coupled conductor simultaneously provides thermal cooling from heat generated by RF dissipative loss. These features may provide a compact, thermally robust power combiner/divider covering 3:1 bandwidth or greater. The devices may be applicable to radar, electronic countermeasures (ECM), and communications transmitters.

  • Patent number: 8427382
    Abstract: To transport electromagnetic energy at high power levels, a coaxial-to-waveguide power combiner/divider comprises a length of single-conductor closed waveguide terminated at one end by a conductive end plate. A plurality N of holes is formed in the end plate. A conductive matching plate is positioned within the waveguide opposite and spaced apart from the conductive end plate and spaced apart from the inner walls of the waveguide. A plurality of coaxial input/output ports each comprise an outer conductor that is electrically and mechanically terminated at the end plate about one hole and an inner conductor that extends through the associated hole into the waveguide and is electrically and mechanically terminated at the underside of the matching plate. The location and geometry of the matching plate and physical arrangement of the N ports are chosen so that the sum of the direct reflection and the N?1 coupled reflection contributions are small.

  • Patent number: 8319581
    Abstract: A power amplifier having multiple solid state sub-amplifiers connected in parallel between an input and an output are described. The signal input to the power amplifier is provided to an RF splitter connected between an input connector and the input of each of the sub-amplifiers. The RF splitter splits the input power from the signal input and provides the power to the sub-amplifier inputs through input electrical paths. The input electrical paths from the power amplifier input to the sub-amplifiers are substantially identical. Each of the sub-amplifiers drive an input of an RF combiner connected between the outputs of the sub-amplifiers and the output of the power amplifier. The RF combiner combines the output power from each of the sub-amplifiers through output electrical paths, and provides the combined power to the power amplifier output. The output electrical paths from the sub-amplifiers to the power amplifier output are substantially identical.
