BRF 900/...-200

Band-Reject Filters for the 900 MHz Band

  • High power base station band-reject filters for the 890 – 960 MHz range.
  • The use of large ø200 mm cavities means a high Q, resulting in a very narrow notch bandwidth.

DESCRIPTION

  • 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.
  • 19” mounting brackets are available as an option.
