TPR 400

400 Watts, 50 Volts, Pulsed

Avionics 1030 - 1090 MHz

GENERAL DESCRIPTION

CASE OUTLINE

The TPR 400 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 junction temperature, extends life.
