GHZ JTDA150A Datasheet
JTDA 150A
145 Watts, 36 Volts, Pulsed
Avionics 960 - 1215 MHz
GENERAL DESCRIPTION
The JTDA-150A is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 960-1215 MHz. The
transistor includes input and output prematch for broadband performance. The
device has gold thin-film metallization and diffused ballasting for proven
highest MTTF. Low thermal resistance S older Sealed Package reduces
junction temperature, extends life.
