Procom BPBR 4-...-125 - Manual

BPBR 4/...-125
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 ø125 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. 4500.
High frequency stability on temperature and power.
19” mounting brackets are available as an option.
