DPBP 2/66-150

High power VHF Duplex Band-Pass Filter incl. Low Pass Filter, for PMR/DMR and Telemetry networks
Description
  • The DPBP 2/66-150 LL/1-…-1/LPF is a 2 x 6 resonator high quality Duplex Band Pass filter designed to combine special custom required Tx and Rx bands to one common antenna.
  • The high performance filter design secures a low Insertion Loss and an improved isolation between the specified Tx and the Rx band.
  • The DPBP 2/66-150 LL/1-…-1/LPF can accomodate a continious power of max. 150 W.
  • The DPBP filter includes a low pass filter for highly attenuating the unwanted 3th. & 5th. harmonics occuring from radio system and the DPBP itselves.
  • The DPBP 2/66-150 LL/1-…-1/LPF filter can be fitted into a 19” mounting tray, 3 HU in height, 600 mm in depth.
