Duplexer VHF 4 Cavity
VHF band-pass/band-reject duplexer designed to provide added protection from out-of-band signals. Fully temperature-compensated 105 mm copper cavity resonators deliver low insertion loss, high rejection, and strong isolation between transmit and receive ports. Each duplexer is designed for a specific band and is supplied as standard in a 3U 19” rack-mountable format.
Model DUP
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. Supplied as standard as 3U 19” rack mountable.
