RF LC Filter & Cavity Filter Product Introduction:
RF LC filters are radio frequency filters composed of passive components such as inductors (L) and capacitors (C). Through frequency selective resonance characteristics, they accurately filter out spurious signals and interference in RF circuits, preserving the target frequency band signal. They are core passive components in the front-end of RF microwave circuits, offering low cost, easy integration, and strong compatibility.
RF LC filters are widely used in: 5G/6G base stations, RF remote radio units (RRU), satellite communication terminals, high-frequency LC filter components, military communication terminals, radar detection equipment, and aerospace RF modules.
Cavity filters are high-performance passive filters in the RF microwave field. They use a metal cavity as a resonant cavity, with built-in resonators. Precise filtering is achieved through cavity shielding and resonant frequency selection, resulting in strong out-of-band rejection, high Q-factor, and low insertion loss. They are core components in medium- and high-frequency high-power RF circuits.
Cavity filters are widely used in: mobile communication base stations, satellite communication and navigation, radar and detection systems, microwave RF communication equipment, and high-power RF terminals.
