500 Watts, 50 Volts, Pulsed
Avionics 1030 / 1090 MHz
GENERAL DESCRIPTION
CASE OUTLINE
The 10500 is a high power COMMON BASE BiPolar transistor. It is
designed for pulsed systems in the frequency band 1025 - 1150 MHz, with the
pulse width and duty required for MODE-S, TACAN & TCAS applications.
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.
