BPF 2/…-125
Band-Pass Filters for the 150 MHz Band
Description
- High power base station band-pass filters for the 140 – 175 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.
