BPF 3/...-200Q-SHT

Band-Pass Filter for the 130 MHz Band

DESCRIPTION

High-power base station shortened band-pass filter for the

118 - 136 MHz range.

During trimming, the threaded rod will externally remain at the same

position - especially beneficial when the cavity is fitted in tight locations

(e.g. in racks).

Due to the use of large ø200 mm cavities a high Q is achieved,

resulting in a very narrow passband.

The large dimensions also mean a high power rating.

The SHT-version has only 600 mm cavity length.

Unloaded Q of a single cavity is approx. 3000.

High frequency stability on temperature and power.

19” mounting brackets are available as an option.
