BPF 900/...-125
Band-Pass Filters for the 900 MHz Band
DESCRIPTION
High power base station band-pass filters for the 800 – 960 MHz range.
The use of large ø125 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. 4500.
High frequency stability on temperature and power.
Mounted on 19" brackets. **
