0912-7
7 Watts, 50 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION CASE OUTLINE
The 0912-7 is a COMMON BASE bipolar t rans i st or. It i s desi gned for
pulsed systems in t he frequency band 960-1215 MHz. The transi st or
includes input pr ematch for broadband capability. The device has gold thin-
film metallization for proven highest MTTF. Low thermal resistance
package reduces junction temperatur e, ext ends li fe.
