45 Watts, 50 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION
The 0912-45 is a COMMON BASE bipolar transistor. It is designed for
pulsed systems in the frequency band 960-1215 MHz. The device has gold
thin-film metallization for proven highest MTTF. The transistor includes
input prematch for broadband capacity. Low thermal resistance package
reduces junction temperature, extends life.
