Compact Base Station Duplexers<\/strong><\/h2>\n

Horwin DF-V\/UM6-x series is compact 6 cavity base station duplex filters. \u201cBand pass\/reject\u201d 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.<\/p>\n

The high Q\u2019s 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 \u2013 low power up to 50 watts continuously and high \u2013 up to 150 watts.<\/p>\n

The filter\u2019s cavities are made of extruded aluminium. All coaxial cables used are semi-rigid silver plated. Cables and connectors are with PTFE insulation. Filters are covered with black polymer powdered coating.<\/p>\n

Each filter is individually made and tuned, so receive and transmit frequencies should be specified when ordering.<\/p>\n

5\u201d Cavity Base Station Duplexers <\/strong><\/h1>\n

Horwin DF-V\/U-x-5 series is a \u201cBand pass\/reject\u201d type duplex filters based on quarter wave 5 inches width square cavities. Duplexer allows simultaneous operation of transmitter and receiver into a single antenna. Using large 5\u201c cavities means very high Q, resulting in very close frequency spacing and low insertion losses. Filters allow to handle up to 150 watts power.<\/p>\n

Cavities are aluminium made with 5 mm thick top plate welded to the cavity body. Inner conductor and coupling loops are silver plated cooper made. Central tuning road is invar made. All this provides excellent frequency stability in temperature range from \u2013 30 to + 60\u00b0C.<\/p>\n

Each filter is individually made and tuned, so receive and transmit frequencies should be specified when ordering.<\/p>\n
