High power base station duplex filter for the 140 - 175 MHz range.
The use of large ø250 mm cavities means a high Q,
resulting in a very narrow duplex spacing.
The large dimensions also mean a high power rating.
Unloaded Q of a single cavity is approx. 8000.
High frequency stability on temperature and power.
Mounted on 19” brackets.
