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.
