Duplexer DPR5-4V is assembled from common 5'' cavities by band pass-reject scheme, enabling to use this duplexer in variety of installations, whether it is full duplex repeater or two radio stations operating with one antenna. Three adjustment levels provide opportunity for precise pass and rejection frequency tuning, and VSWR, loss level and gain slope tuning, also. Implemented temperature compensating techniques enable to use the device in not heated locations (garrets, television and radio towers top decks, etc.). Duplexer attachment points enable to mount it into standard 19-inch repeater rack. Duplexer DPR5-6V has higher characteristics at corresponding loss.
