GENERAL DESCRIPTION

The TPR400A 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. Low

thermal resistance packaging reduces the junction temperature and extends

device lifetime.
