BPF 70/...-200
Band-Pass Filters for the 450 MHz Band
DESCRIPTION
High power base station band-pass filters for the 380 - 470 MHz range.
The use of large ø200 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. 7000.
High frequency stability on temperature and power.
19” mounting brackets are available as an option.
