DME 150
150 Watts, 50 Volts, Pulsed
Avionics 1025 - 1150 MHz
GENERAL DESCRIPTION
The DME 150 is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 1025-1150 MHz. The
device has gold thin-film metallization and diffused ballasting for proven
highest MTTF. The transistor includes input and ouput prematch for
broadband capabilit. Low thermal resistance package reduces junction
temperature, extends life.
