BPF 3/…-250
Band-Pass Filters for the 130 MHz Band
Description
- High power base station band-pass filters for the 116 – 146 MHz range.
- The use of large ø250 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 better than 8000.
- High frequency stability on temperature and power.
- 19” mounting brackets are available as an option.
