Duplexers

Shop RF duplexers for base stations, repeaters, two-way radio systems, public safety networks and wireless communications infrastructure. Duplexers allow transmit and receive signals operating on separate frequencies to share a common antenna while maintaining separation between the RF paths.

Radio duplexers use frequency-selective filtering to route signals between the transmitter, receiver and antenna ports. They are commonly used where simultaneous transmission and reception are required through one antenna system, helping reduce the need for separate transmit and receive antennas.

Browse antenna duplexers and base station duplexers for VHF, UHF, cellular and other wireless frequency applications. Important selection factors include the operating frequencies, frequency spacing, insertion loss, isolation, power rating, connector interface and intended system configuration.

Explore related RF combiners, cavity combiners, crossband couplers and hybrid couplers. These passive RF components support signal routing and frequency management across telecommunications systems.
