A power sampler may include a sampling circuit interposed in one leg of a differential-signal circuit. An input balun may convert a single-ended signal from a signal source into a differential signal on first and second differential-signal input ports. An output balun may convert an output differential signal to a single-ended output signal to a signal load. The sampling circuit may include an inductance and a coupling circuit. The inductance may be an inductor and have an impedance higher than a source impedance. The coupling circuit, which may be a balun, is connected to the inductance and outputs a single-ended sample signal having a magnitude proportional to the inductance impedance at the design frequency. A second coupling-circuit output conducts an output differential signal and may be connected to the output balun.

In some embodiments, a power divider/combiner assembly includes a divider network, a plurality of amplifiers, and a combiner network. The divider network divides a received divider-network input signal into N divider-network output signals. The divider network includes at least one divider and at least one divider phase-shift circuit. The plurality of amplifiers include N amplifiers for amplifying the divider-network signals. The combiner network is for combining the N amplified signals into a combiner-network output signal. The combiner network includes at least one combiner and at least one combiner phase-shift circuit. Each phase-shift circuit is configured to produce a respective non-zero phase shift between divider output signals or between combiner input signals.

Phase-shifting power divider/combiner assemblies and systems

A non-directional tap coupler for use in high power operation over a wide bandwidth is provided. The tap coupler has an input line electrically connectable to a transmission line of a distributed transmission line system, a tap line coupled to the input line and an output line coupled to the input line. The input line, tap line and output line include sections having different characteristic impedances, with all of the different characteristic impedances falling within a practical characteristic impedance range. An electrical junction where the input line electrically joins the tap line and the output line is provided with a predetermined impedance value to ensure that the sections of the tap line and the output line all fall within the practical characteristic impedance range.
