Diamond Rf? Resistives:The Answer to High Power and Low Capacitance

摘要

A single 0402 resistor, manufactured on a CVD diamond substrate, can dissipate 20 W of continuous electrical energy and 200 W of pulsed energy. This provides great flexibility to the design engineer, who is continually asked to reduce size and increase performance. This article describes the current power resistor implementations, the limitations of conventional power resistors and shows how diamond passive components can provide a path to reduce the limitations in real applications.
