PRO-DPBP 380-EXT

Duplex Band-Pass Filter, PIM rated, for the TETRA Public Safety/Mission Critical extended band
Description
  • 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.
