BPBR 70/...-125

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 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.

Mounted on 19" brackets. **
