Horwin Base Station Duplexers

Horwin DF-V/UM6-x series is compact 6 cavity base station duplex filters. “Band pass/reject” duplexer is ideal for repeaters, duplex base stations and other applications when combining of both receive and transmit frequencies into a single antenna is needed. The high Q’s of the filter enable the duplexer to work with narrow duplex spacing and to keep low insertion losses. There are two model versions regarding power handling capability – low power up to 50 Watts and high – up to 150 Watts.

Each filter is individually made and tuned, so receive and transmit frequencies should be specified when ordering.
