Filter
The working frequency band of the 5G communication base station overlaps with the 3.4-4.2GHz satellite signal frequency band by nearly 300MHz. Microwave interference and pulse interference appear at the receiving end of the C-band satellite communication, which seriously affects the quality of satellite signal reception. Data packet loss is very serious, and even This will cause signal mosaic or interruption, which will have a great impact on the signal receiving work of radio and television, financial institutions, and meteorological agencies.
Therefore, the interference suppression satellite filter of the C-band satellite signal integrated receiving decoder is required, and its working bandwidth is 3625-4200MHz, 3700-4200MHz (satellite earth station C-band), which requires good in-band flatness and high out-of-band suppression efficiency.

At present, the cavity waveguide bandpass filter is mainly used. Its working principle is to induce the vibrator of the corresponding frequency through electromagnetic waves, usually a level 5 vibrator, and the signal attenuation is slightly larger. The advantage is that the cavity waveguide is relatively long, which is effective for areas with strong interference signals. Very good anti-jamming effect.
