Abstract

The invention provides an asymmetric multichannel radio frequency switch matrix device. The device comprises a PCB, a controller, N radio-frequency signal input ends, N radio-frequency signal output ends and 2N radio-frequency switches, the PCB comprises a surface signal layer and a bottom signal layer, the controller is connected with the 2N radio-frequency switches, and each radio-frequency switch is provided with N signal channels. According to the asymmetric multichannel radio frequency switch matrix device, the radio frequency signal input end and the radio frequency signal output end arearranged perpendicular to each other, so that the input signal line and the output signal line are also perpendicular to each other, the radio frequency wiring does not intersect on the surface signal layer and the bottom signal layer, the requirement for the number of layers of the PCB is low, and the size and cost of the multichannel radio frequency switch matrix are reduced.

Description

technical field [0001] The invention relates to the technical field of radio frequency switch matrix, in particular to an asymmetric multi-channel radio frequency switch matrix device. Background technique [0002] Switch matrices are often used in automatic test equipment for various electronic equipment such as radar, communication, electronic countermeasures, identification friend or foe, and precision guidance. Switch matrices can quickly switch signal flows and are an indispensable part of channel switching in these systems. With the continuous improvement of the integration level of automated test equipment, the requirements for the switch matrix are getting higher and higher. First, the number of switch matrix channels is increasing, and second, the volume of the switch matrix is ​​getting smaller and smaller. [0003] At present, in the multi-channel switch matrix, the symmetrical structure of the input end and the output end is usually adopted, so that the PCB RF tr...
