Horwin DF-V/U-x-5 series is a “Band pass/reject” 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“ cavities means very high Q, resulting in very close frequency spacing and low insertion losses. 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 – 30 to + 60°C. Each filter is individually made and tuned, so receive and transmit frequencies should be specified when ordering.

Pairing is achieved with bearings of identical tolerance classes and by applying an axial preload to the inner rings for the O arrangement and on the outer rings for the X arrangement. The inner or outer rings are undergo a separate grinding operation to align both side faces on the same plane with minimum clearance.
