BPBR 4/...-250

Band-Pass/Band-Reject Filters for the 80 MHz Band

DESCRIPTION

High power base station band-pass/band-reject filters for the 66 – 88

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.
