  • High power base station band-pass/band-reject filters for the
  • 66 – 88 MHz range.
  • The use of large ø200 mm cavities means a high Q, resulting
  • in a very narrow pass/reject spacing.
  • 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.
