High-power-density 4H-SiC RF MOSFETs
IEEE Electron Device Letters, 2006We have made a 4H-SiC RF power MOSFETs with cutoff frequency up to 12 GHz, delivering RF power of 1.9 W/mm at 3 GHz. The transistors withstand 200 V drain voltage, are normally-off, and show no gate lag, which is often encountered in SiC MESFETs. The measured devices have a single drain finger and a double gate finger and a total gate width of 0.8 mm ...

Power MOSFETs Paralleling Operation for High Power High Density Converters
Conference Record of the 2006 IEEE Industry Applications Conference Forty-First IAS Annual Meeting, 2006In high power high density converters, the power MOSFETs can be used in parallel as the main switch to meet the current rating requirement, increase the switching frequency, and reduce the power loss. This paper investigates the possible benefits and problems associated with the power MOSFETs paralleling operation for higher power high frequency ...

High Power/Torque-Density Devices
2020Mechanical power transmission and handling devices are evaluated according to their power density, or else their torque density if it is not the power that is the issue of primary concern. The combination of high power or torque density with good energy efficiency may collectively be termed high-performance density.
