RF Cavity Filters

RF Cavity Filters


RFecho RF Cavity Filters are known for their low insertion loss and higher power handling ability. Cavity filters are one of many types of RF Filters and are one of the fundamental building blocks of modern communications systems, and they are the basic circuitry behind a duplexer and are sharply tuned resonant circuits that allow only certain frequencies to pass. Cavity filters are resonant filters utilized for passing the desired RF signals within a specified frequency range or rejecting RF signals within a range of frequencies. The resonant cavity inside these filters can be made from strong materials, like highly conductive and dimensionally stable metals, to dependably perform for a long time.

RFecho manufactures premium quality RF Filter and products technical support to customers for matching the exact requirement of the application.

Cavity filter types:

Low Pass Filter, High Pass Filter, Cavity Band Reject Filter, and Cavity Band Pass Filter.


  • Increase peak power handling
  • Reduced Size
  • Lightweight
  • Enhanced Rejection
  • Minimal Temperature Drift

RF Cavity Filter selection varies greatly depending on the application i.e. size, power handling, frequency range, noise addition, etc. Popular use of these filters includes television, mobile, satellite communications, and radar applications. RFecho provides from individual products to solution package for your requirements.
