UMIL10P

10 Watts, 28 Volts, Class AB

UHF Communications 100 – 400 MHz

GENERAL DESCRIPTION

The UMIL10P is a COMMON EMITTER broadband transistor specifically

intended for use in the 100-400 MHz frequency band. It may be operated in

Class AB or C.

Gold metallization and silicon diffused resistors ensure

ruggedness and high reliability.
