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.
