Abstract:

Sanders role on this program was to produce an electronic assembly that would demonstrate the performance benefits gained by incorporating diamond materials into critical electronics assemblies. The power regulator hybrid for the F-22 EW Array electronics was identified as an ideal candidate. The power regulator hybrid provides regulation and distribution of seven discrete voltages to supply RF and analog electronics for the EW array. Power dissipation is over 60 Watts for this assembly, making thermal management a major priority of the design. By inserting diamond substrates, silicon device junction temperatures could in principle be significantly reduced, improving overall reliability of the assembly.
