25 Watts, 28 Volts, Class AB

Defcom 225 - 400 MHz

GENERAL DESCRIPTION

The UMIL 25 is an input matched COMMON EMITTER broadband

transistor specifically intended for use in the 225-400 MHz frequency

band. It may be operated in Class AB or C. Gold metallization and

silicon diffused resistors ensure ruggedness and high reliability.
