10502 - Advanced Power Technology

10502

500 Watts, 50 Volts, Pulsed

Avionics 1030 / 1090 MHz

GENERAL DESCRIPTION

The 10502 is a high power COMMON BASE bipolar transistor. It is designed

for pulsed systems in the frequency band 1030/1090 MHz, with the pulse width

and duty required for MODE-S &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.
