DME800 800 Watts, 50 Volts Pulsed Avionics 1025 to 1150 MHz GENERAL DESCRIPTION CASE OUTLINE 55ST-1 (Common Base) The DME800 is a high power COMMON BASE bipolar transistor. It is designed for pulsed DME systems at 1025 to 1150 MHz, with the pulse width and duty required for DME applications. The device has gold thin-film metalization for proven highest MTTF. The transistor includes input and output prematch for broadband capability. Low thermal resistance package reduces junction temperature, extends life.
