Duplexer DPR8-4V assembled from high-Q 8-inch diameter cavities by band pass-reject scheme. It has three level of adjustment: frequency, separation TX/RX value, rejection and pass level. It’s designed to provide full-duplex operation for one antenna of repeater or radio station with high power output. Used commonly under nonstandard frequency separation conditions.
Implemented temperature compensating (thermostable) techniques enable to use the device in not heated locations. Duplexer attachment points enable to mount it into standard 19-inch repeater rack.
DPR8-4(6)V provides duplex operation at lower frequency separation, unlike duplexers assembled on 5-inch cavities
