0912-7

7 Watts, 50 Volts, Pulsed

Avionics 960 - 1215 MHz

GENERAL DESCRIPTION CASE OUTLINE

The 0912-7 is a COMMON BASE bipolar transistor. It is designed for
pulsed systems in the frequency band 960-1215 MHz. The transistor
includes input prematch for broadband capability. The device has gold thin­film metallization for proven highest MTTF. Low thermal resistance
package reduces junction temperature, extends life.
