The function of the cavity band-stop filter is exactly the opposite of the band-pass filter, which suppresses signals in a certain frequency band and allows signals outside this frequency band to pass. That is, filter out the middle frequency band and retain the high and low frequencies. Can be customized according to customer needs.
