Description

The 20W RF Cavity Duplexer is a passive RF component designed to allow a transmitter and receiver to share a common antenna while operating on separate frequency channels. Its cavity-based filtering structure provides frequency selectivity, helping isolate transmit and receive signals and reduce unwanted interference in compatible communication systems. This duplexer is suitable for RF communication equipment, wireless radio systems, repeater installations, and other applications requiring separate transmit and receive frequency paths. It helps route signals between the transmitter, receiver, and shared antenna while supporting reliable system operation. Designed for applications with a specified power rating of 20 W, the RF Cavity Duplexer uses resonant cavities to provide frequency filtering and isolation. Its performance depends on the operating frequency bands, channel spacing, cavity design, and system configuration. Important technical parameters include transmit and receive frequency ranges, insertion loss, isolation, return loss, VSWR, bandwidth, impedance, and maximum power-handling capacity. Correct frequency tuning and installation are essential for achieving the required performance. Before ordering, verify the transmit and receive frequencies, channel spacing, bandwidth, 20 W power rating, connector type, impedance, and tuning requirements against the manufacturer's datasheet. Confirm whether the 20 W rating applies to continuous or peak power and ensure compatibility with the intended RF system.
