Abstract
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.
