TPR 500A
500 Watts, 50 Volts, Pulsed
Avionics 1030 - 1090 MHz
GENERAL DESCRIPTION
The TPR 500A 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 and diffused ballasting for proven
highest MTTF. The transistor includes input prematch for broadband
capaility. Low thermal resistance package reduces junction temperature,
extends life.
