TCS800

800 Watts, 50 Volts, Pulsed

Avionics 1030 MHz

R.-.061300

GENERAL DESCRIPTION

The TCS800 is a high power COMMON BASE bipolar transistor. It is

CASE OUTLINE

55SM Style 1

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 MT TF. The transistor
includes input and output prematch for broadband capability. Low thermal
resistance package reduces junction temperature, extends life.
