Procom BRF 900-...-200 - Manual

BRF 900/...-200
Band-Reject Filters for the 900 MHz Band
DESCRIPTION
High power base station band-reject filters for the 890 – 960 MHz range.
The use of large ø200 mm cavities means a high Q,
resulting in a very narrow notch bandwidth.
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.
