0912-7
7 Watts, 50 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION
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 thin-
film metallization for proven highest MTTF. Low thermal resistance
package reduces junction temperature, extends life.
