MDS1100 1100 Watts, 50 Volts Pulsed Avionics at 1030 MHz GENERAL DESCRIPTION CASE OUTLINE 55TU-1 The MDS1100 is a high power COMMON BASE bipolar transistor. It is designed for pulsed systems at 1030 MHz, with the pulse width and duty required for MODE-S applications. The device has gold thin-film metalization and emitter ballasting for proven highest MTTF. The transistor includes input and output prematch for broadband capability. Low thermal resistance package reduces junction temperature, extends life.
