cavity filter

cavity filter

[′kav·əd·ē ‚fil·tər]
(electromagnetism)
A microwave filter that uses quarter-wavelength-coupled cavities inserted in waveguides or coaxial lines to provide band-pass or other response characteristics at frequencies in the gigahertz range.

The original formulation was further developed in granulated form so that it could be inserted in a cavity filter.
Further broadening of the application of RF MEMS devices is evident in a paper presenting MEMS-based tuning of an evanescent-mode cavity filter at 5 GHz with Qs greater than 500 and switch matrices up to 4-by-4 based on switch elements with less than 2 db of insertion loss up to 40GHz [TH2E-3].
