BPBR 70/...-250
Band-Pass/Band-Reject Filters for the 450 MHz Band
DESCRIPTION
High power base station band-pass/band-reject filters for the 380 – 470
MHz range.
The use of large ø250 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. 8000.
High frequency stability on temperature and power.
19” mounting brackets are available as an option.
