250 Watts, 50 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION CASE OUTLINE
The TAN 250A is a high power COMMON BASE bipolar transistor. It is
designed for pul sed sy stem s in the frequency band 960-1215 MHz . The
device has gold thin-fi lm metallization and diffused ballasting for proven
highest MTTF. The transistor includes input output prematch for broadband
capability. Low thermal resistance package reduces junction temperature,
extends life.
