Cavity Filters
RFI offers a range of quality temperature compensated cavity filters in Band Pass, Standard Notch, Series Notch®, Vari-Notch® and T-Pass® styles. The wide range of cavity filters are used as building blocks for duplexers, pre-selectors, combiners and generally combating interference either as a high "Q" notch or as a single or series band pass filter combination.
If the cavity filter you require is not shown here, please contact your local RFI sales office.
