Band Pass FiltersPRO-BPF 451-466-LP

Band-Pass Filter for the LTE band 451 - 466 MHz

Description

Interference originating from DVB-T transmitters can often lead to saturation of LTE450 receivers disrupting communication reception and reducing radio coverage. The new mast mountable bandpass filter, PRO-BPF 451-466-LP is designed to suppress high power signals, effectively mitigating interference, and elevating the performance of LTE450 communications. Covering LTE bands 31 and 72. Key Features:
  • PRO-BPF 451-466-LP (Low Pim) is a robust high performance UHF 450 MHz band-pass filter for mounting e.g. in base station masts.
  • It is highly used for protecting the recieving side of a LTE radio system or other DMR systems from high power out of band interference occuring from e.g. DVB-T systems or others.
  • PRO-BPF 451-466-LP is PIM rated to -150 dBc @ 2 x 20 W (2 x 43 dBm).
  • The Band-Pass Filter is built into a IP67 proof enclosure for wall mounting or it can be mounted on masts or pylones. See the Mechanical designation.
  • Covers LTE450 band 31 and 72 (451 - 466 MHz)
  • Mast mountable – brackets and metal strips included for mounting.
