GHz JTDB75 High power common base bipolar transistor. Datasheet

JTDB 75
75 Watts, 36 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION
The JTDB 75 is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 960-1215 MHz. The
device has gold thin-film metallization and diffused ballasting for proven
highest MTTF. The transistor includes input and output prematch for
broadband capability. Low thermal resistance package reduces junction
temperature, extends life.
