TAN 250A
250 Watts, 50 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION CASE OUTLINE
The TA N 250A i s a high power COMMON BA SE bi polar tra nsistor. It is
des igne d 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 output prematch for broadband
capability. Low thermal resistance package reduces junction temperature,
extends life.
