BRF 900/…-125
Band-Pass/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 ø125 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. 4500.
- High frequency stability on temperature and power.
- 19” mounting brackets are available as an option.
