450 Watts, 45 Volts, Pulsed
Avionics 1030 MHz
GENERAL DESCRIPTION
CASE OUTLINE
The TCS450 s 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 TCAS applications. 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.
