Procom BPF 3-...-200q-sht - Manual

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.
