A versatile monolithic RF amplifier using a dielectrically isolated monolithic microwave integrated circuit (DIMMIC)

Abstract

A new RF integrated-circuit technology is described that overcomes the drawbacks of currently available integrated processes. This DIMMIC technology draws its advantage from its dielectric isolation, which minimizes parasitic substrate capacitance, and from its lack of increased collector resistance. Using this technology, a medium-power RF amplifier was built that reduced parts count and size significantly over its discrete counterpart without sacrificing performance.<>
