Abstract

The invention discloses a method for performing gold backing on a printed circuit board of a Ku waveband microstrip type switch circuit, which selectively performs gold backing treatment on the printed circuit board in the process of performing the gold backing treatment on the printed circuit board in the Ku waveband microstrip type switch circuit so as to separate the part between the printed circuit board and the back face of a microstrip line grounded base plate, inhibit the coupling effect of microwave signals, avoid the introduction of more parasitic parameters in the circuit, and improve the isolation performance of the microstrip type switch circuit. The method effectively inhibits the coupling effect of the microwave signals, avoids the introduction of more parasitic parameters in the circuit, and finally improves the isolation performance of the microstrip type switch circuit. The method has the characteristics of simple manufacturing, good repeatability, low cost, wide application range and the like.

Description

technical field

[0001] The invention relates to the technical field of design of a Ku-band microstrip switch circuit, in particular to a method for backing a printed circuit board of a Ku-band microstrip switch circuit. Background technique

[0002] In radar transmitter systems, satellite communications and various communication and navigation electronic warfare systems, microwave switch circuits are widely used to realize the on, off or conversion of microwave signals. At present, when the microstrip switching circuit based on the PIN switching diode is applied in the microwave frequency band, there are some coupling effects caused by the microwave signal radiation due to the significant difference between the high-frequency microwave signal and the low-frequency AC or DC signal. As the frequency increases, this effect will have a greater impact on the circuit performance, resulting in a large gap between the theoretical design of the switching circuit and the actual debugg...
