BRF 2/...-200

Band-Reject Filters for the 150 MHz Band

DESCRIPTION

High power base station band-reject filters for the 140 - 175 MHz range.

The use of large ø200 mm cavities means a high Q,

resulting in a very narrow passband.

The large dimensions also mean a high power rating.

Unloaded Q of a single cavity is approx. 7000.

High frequency stability on temperature and power.

19” mounting brackets are available as an option.
