JTDB75
75 Watts, 36 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION
The JTDB75 is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 960-1215 MHz. The dev ice
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.
