RF Cavity Filters

Cavity Filter

Cavity Filters from RFecho 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.

RF Cavity Filters 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 Cavity Filters and products technical support to customers for matching the exact requirement of the applications.


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