Cavity Filters High Rejection & Selectivity Cavity filters achieve much higher Q, steeper rejection skirts, and higher power handling than other filter technologies, such as ceramic resonator filters, and are utilized where low passband insertion loss and high rejection of neighboring channels/spurious emissions are critical. Applications include military and commercial fixed site and mobile networks, as well as satellite communications.
