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.**
