Filter is an important component used to separate or assemble different frequency signals in the microwave system. It has frequency-selected function, inhibiting the unwanted frequency signals and selecting inundated signals. Adopting the high Q value structure, filter has the characteristics of low standing wave, low insertion loss, high working power, etc. There are four types of filters: high pass, low pass, pass-band and stop-band. Pass-band filters are usually used.
