摘要： A combiner/divider includes a plurality of input/output waveguides distributed in a plane and diverging in at least a partially common direction away from a central point. Each input/output waveguide extends from an outer node disposed distal of the central point to an inner port proximate to and spaced from the central point. Each input/output waveguide has a respective dimension in the plane that increases between the inner port and the outer node. An output/input waveguide has an aggregate port proximate to the central point and facing the inner ports. A transition waveguide defines an open cavity that flares outwardly in the plane from the aggregate port toward the inner ports and communicatively couples the output/input waveguide with the input/output waveguides. Opposing distal surfaces of the transition waveguide and inner port edges are spaced apart by a distance that decreases with increasing distance from the aggregate port.

摘要： A transmission-line-based impedance transformer including first and second couplers, with each coupler including respective pairs of coupled signal conductors. The signal conductors are connected sequentially in series between an input port and an output port and may form a single spiral configuration. A signal conductor of one coupler may be connected in series between the two signal conductors of another coupler. The couplers have characteristic impedances between an input impedance and an output impedance. A signal conductor of a coupler may include first and second conductor portions disposed in respective spaced-apart parallel planes, with the other signal conductor of the coupler disposed physically directly between the first and second conductor portions. A transmission-line signal conductor in the spiral may be shielded from coupled signal conductors by ground conductors disposed in respective spaced-apart parallel planes on opposite sides of the shielded signal conductor.

摘要： 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.

摘要： A multilayer capacitor may include a capacitor stack having pluralities of first and second plate electrodes connected to respective stack face terminals. Two face terminals on different stack sides are connected to the first plate electrodes. Two different face terminals also on different stack sides are connected to the second plate electrodes. Respective base conductors connect to the two sets of face terminals for connecting the capacitor to an external circuit. Three face terminals may be connected to the first or second plate electrodes. The base conductors may connect to the face terminals at the same relative position of the capacitor stack, at different relative positions of the capacitor stack. A capacitor stack may be positioned with a stack end facing a base substrate. Two multilayer capacitors may be mounted electrically in parallel with one or more lossy elements spanning a gap between the capacitors.

摘要： A multilayer coupler may include electromagnetically coupled planar first and second signal conductors that are separated by a gap, extend adjacent each other along a ground plane, and change orientation in a bend. A plate may be positioned along the bend between the ground plane and the signal conductors. The ground plane may have an opening extending along the bend and the plate. A multilayer coupler may include two coupled signal conductors formed in a loop having a four-wire section in which different sections of the two signal conductors overlap in a four-wire section. In a transition region in which the coupler transitions from the four-wire section to a two-wire section, an isolating ground plane may separate the two two-wire sections extending from the four-wire section. A bend in the transition region may include a plate between the two signal conductors and the ground plane.
