Band Pass FiltersBPF 3/...-200

Band-Pass Filters for the 130 MHz Band

Description

  • High power base station band-pass filters for the 116 - 146 MHz range.
  • The use of large ø200 mm cavities means a high Q,
    resulting in a very narrow passband.
  • The large dimensions also mean a high power rating.
  • Unloaded Q of a single cavity is better than 6000.
  • High frequency stability on temperature and power.
  • 19” mounting brackets are available as an option.
