MDS170L
170 Watts, 36 Volts, Pulsed
Avionics 1030/1090 MHz
GENERAL DESCRIPTION
The MDS170L is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 1030 - 1090 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 Solder Sealed Package reduces
junction temperature, extends life.
