R.-.061300 TCS800 800 Watts, 50 Volts, Pulsed Avionics 1030 MHz GENERAL DESCRIPTION CASE OUTLINE 55SM Style 1 The TCS800 is a high power COMMON BASE bipolar transistor. It is designed for pulsed systems in the frequency band 1030 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 and output prematch for broadband capability. Low thermal resistance package reduces junction temperature, extends life.
