MDS170L

www.DataSheet4U.com 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.
