TPR 500
500 Watts, 50 Volts, Pulsed
Avionics 1030 - 1090 MHz
GENERAL DESCRIPTION
The TPR 500 is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 1030-1090 MHz. The
device has gold thin-film metallization for proven highest MTTF. The
transistor includes input prematch for broadband capability. Low thermal
resistance package reduces j unction temperature, extends life.
