RFI Filters are widely used in wireless communications systems to pass the desired spectrum and reject the unwanted frequencies and/or interference.
Filters can be used as receiver preselectors or transmit post filters cleaning up power transmitter carriers or Tx sub-bands.
Filters are available in multiple types of frequency responses such as bandpass and notch. They are available in various power ratings and in either cavity configurations or as compact milled aluminium filters to cater for a wide variety of applications.
