BPBR 3/...-250

Band-Pass/Band-Reject Filters for the 130 MHz Band

  • High power base station band-pass/band-reject filters for the 116 – 146 MHz range.
  • The use of large ø250 mm cavities means a high Q, resulting in a very narrow pass/reject spacing.

DESCRIPTION

  • The large dimensions also mean a high power rating.
  • Unloaded Q of a single cavity is approx. 8000.
  • High frequency stability on temperature and power.
  • 19” mounting brackets are available as an option..
