PRO-DPBP 380-EXT - Duplex Filters

The PRO-DPBP 380-EXT is a 2 x 6 resonator high quality Duplex Band Pass filter designed to combine the TETRA extended Tx and Rx band (2 x 6.5 MHz) to one common antenna. The high performance filter design secures an improved isolation between the Tx and the Rx TETRA band. It is common used in high power Tetra base stations. A pure silver-plating inside the filter ensures a very low PIM and insertion loss. The filter uses reduced-length ¼ λ cavities in a compact strong aluminium housing. The compact filter will fill in 2 HU in height, 142.5 mm in depth, in a 19" rack, when mounted on a 19" x 2 HU front plate. When mounted in a 19” mounting tray, 300 mm in depth, the total height will be 3 HU.
