RF DME500 500 watts, 50 volts, pulsed avionics 1025 - 1150 mhz Datasheet

DME 500
500 Watts, 50 Volts, Pulsed
Avionics 1025 - 1150 MHz
GENERAL DESCRIPTION
The DME 500 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 for proven highest MTTF. The
transistor includes input and output prematch for broadband capability. Low
thermal resistance package reduces junction temperature, extends life.
