This VHF duplexer design is a band pass band reject which provides additional protection from out of band signals. Fully temperature compensated 105mm copper cavity resonators ensure low insertion loss, high rejection and very good isolation between the transmit and receive ports.
Each duplexer is designed for a particular band. Please specify Tx and Rx frequencies when ordering. Supplied as standard as 3U 19” rack mountable.
