The function of this cavity band-stop filter is the complete opposite of a band-pass filter: it can suppress signals within a specific frequency range while allowing signals outside that frequency range to pass through. In other words, it can filter out mid-frequency signals and retain high- and low-frequency signals. This filter can be customized according to the customer's requirements.
