UMIL 70
70 Watts, 28 Volts, Class AB
Defcom 225 - 400
GENERAL DESCRIPTION
The UMIL70 is a double 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.
