BPF 3/…-200-SHT

Band-Pass Filter for the 130 MHz Band
Description
  • High power base station shortened band-pass filter for the 116 – 146 MHz range.
  • Due to the use of large ø200 mm cavities a high Q is achieved, resulting in a very narrow passband.
  • The large dimensions also mean a high power rating.
  • The SHT-version has only 600 mm cavity length.
  • Unloaded Q of a single cavity is approx. 3000.
  • High frequency stability on temperature and power.
  • 19” mounting brackets are available as an option.
