Band Pass FiltersBPF 1/...-200

Band-Pass Filters for the 225 - 400 MHz Band

Description

  • High power base station band-pass filters for the 225 - 400 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 approx. 7000.
  • High frequency stability on temperature and power.
  • Mounted on 19” brackets. **
  • ** See "CAVITY MOUNTING OPTIONS" ( ø200 cavity)
