Metal cavity duplexer combines two metal cavity filters—typically a transmit filter and a receive filter—into a single unit with a common antenna port. It allows simultaneous transmission and reception over a single antenna while providing high isolation between the TX and RX paths. With its low insertion loss and high power handling, it is widely used in base stations, repeaters, and other high-power wireless communication systems.
