DME150

DME 150 150 Watts, 50 Volts, Pulsed Avionics 1025 - 1150 MHz www.datasheet4u.com 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.
