Abstract

The invention provides a single-excitation micro-discharge radio frequency noise signal suppression method and device. The device includes a microwave device and a filter. The rear end of the microwave device is connected in series with the filter. A frequency parameter of the filter is determined according to frequency of a radio frequency noise signal generated by the microwave device under single excitation so as to suppress the radio frequency noise signal. Since the frequency of the radio frequency noise signal generated by the microwave device under single excitation is within a passingforbidding frequency range defined by the frequency parameter of the filter, the filter can accurately suppress the radio frequency noise signal. Therefore, the single-excitation micro-discharge radiofrequency noise signal suppression method and device have a good radio frequency noise signal suppression effect.

Description

technical field [0001] The invention relates to the technical field of radio frequency noise signal measurement, and more specifically, to a method and device for suppressing radio frequency noise signals of single-excitation micro-discharge. Background technique [0002] During the use of microwave devices, secondary electron emission and avalanche discharge may occur. This phenomenon is micro-discharge effect, which will generate radio frequency noise signal to interfere with communication. In order to avoid radio frequency noise signal interference, related technologies are generally limited to chemically treating the surface of microwave devices to suppress radio frequency noise signals. Specifically, the surface of microwave devices is mainly chemically treated by the following two methods: [0003] The first method uses chemical methods to micro-etch the aluminum alloy surface of the microwave device to form nano-micro traps on the surface to suppress the external ra...
