PRO-BPF 118-137-N

Band-Pass Filter for 118 - 137 MHz

  • PRO-BPF 118-137-N is a rugged 6-resonator combline band-pass filter for handling high power levels.
  • Allows the whole 118 – 137 MHz band to pass with low loss.

DESCRIPTION

  • No spurious responses below 900 MHz.
  • Can be used as transmit filter to prevent out-of-band and harmonics radiation.
  • Can be used as a preselector to protect a receiver against interferences from transmitters normally being outside the band-pass range.
  • N connectors for strong and reliable coupling to the surroundings.
  • PRO-BPF 118-137-N is lacquered with black vinyl enamel to avoid corrosion.
