摘要： An enhanced electrical circuit can employ conductive fill components that can facilitate providing desirable resistive stabilization of the electrical circuit and other desirable circuit qualities without having to use a physical resistor. The electrical circuit can comprise a transmission line, which can be a microstrip line, that can have defined dimensions. The electrical circuit can comprise respective conductive fill components that can be in proximity to desired sides of the transmission line, wherein the respective conductive fill components can provide the desired resistive stabilization for the electrical circuit. The respective conductive fill components can be separated from, and not in contact with, each other based on respective gaps of a defined size(s) between respective adjacent conductive fill components. The respective conductive fill components can be across a single layer or multiple layers of conductive fill components.

摘要： A substrate includes, two first through-holes to which high-frequency signals are transmitted and which are arranged side by side so as to have a predetermined distance, and at least three reference potential second through-holes arranged side by side so as to have an distance smaller than the predetermined distance with respect to the two first through-holes. Among three of the second through-holes, one of the second through-holes is arranged in a region between the two first through-holes, and other two of the second through-holes are arranged in a region other than the region between the first through-holes such that one of the other two second through-holes is arranged side by side with respect to one of the two first through-holes, and the other of other two second through-holes is arranged side by side with respect to the other of the two first through-holes.

摘要： The accuracy of an impedance tuner may be improved and the size may be reduced by using linear actuators instead of rotary motors. The linear actuator may be integrated with position sensors to allow very small size, and implemented with a servo system for best accuracy and speed. Spring loaded arms holding the mismatch probes allow the tuner to operate in any orientation to further fit into small spaces. The small size reduces losses by allowing direct connection to wafer probes for on-wafer measurement systems.

摘要： A routing structure of a two-core parallel shielded electric wire includes: two insulated electric wires that are arranged in parallel; and a shield layer that is attached around the two insulated electric wires and extends in a longitudinal direction of the two insulated electric wires. In the routing structure, the two-core parallel shielded electric wire is rerouted by bent twisting the two-core parallel shielded electric wire in a short axis direction at a route change point along a long axis direction of the two-core parallel shielded electric wire, and the number of bent twisted points in the short axis direction is 1.43 or less per meter.

摘要： In an example embodiment, an azimuth combiner comprises: a septum layer comprising a plurality of septum dividers; first and second housing layers attached to first and second sides of the septum layer; a linear array of ports on a first end of the combiner; wherein the first and second housing layers each comprise waveguide H-plane T-junctions; wherein the waveguide T-junctions can be configured to perform power dividing/combining; and wherein the septum layer evenly bisects each port of the linear array of ports. A stack of such azimuth combiners can form a two dimensional planar array of ports to which can be added a horn aperture layer, and a grid layer, to form a dual-polarized, dual-BFN, dual-band antenna array.

摘要： A transmission device is enabled to satisfactorily detecting whether or not a reception device is in the operating state even in a case where an element that adjusts signal quality is interposed in a data line. A cable is connected between the transmission device and the reception device. The element that adjusts signal quality is interposed in the data line. A detection unit detects that the reception device is in the operating state. An information supply unit supplies detection information to the transmission device through a predetermined line.
