Introduction to the MPM: what it is and where it might fit

The microwave power module (MPM) is introduced and described. Its synergistic combination of technologies-MMIC (monolithic microwave integrated circuit) driver, vacuum power booster, and integrated electronic power conditioning-has a multitude of advantages for system applications. The MPM is capable of achieving performance not attainable with either solid-state or vacuum-electronics technology alone. Anticipated power, efficiency, and noise performance in the 6- to 18-GHz band in a compact lightweight package will be suitable for selected radar and EW (electronic warfare) applications. The second-generation MPM will be even more capable and suitable for insertion in a wider range of systems. The background of the MPM Program is detailed, and MPM programmatics are presented. Technical challenges that must be met in a variety of technical areas are identified.<>
