Procom BPF 3-...-125 - Manual

BPF 3/...-125
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 ø125 mm cavities gives 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.**
