UMIL 25
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.
