Advancements in semiconductor technology have led to a steady increase in the unity power gain frequency (fmax) of silicon transistors, both in CMOS and SiGe BiCMOS technologies. This, in turn, enables realization of complex monolithic silicon integrated circuits operating at the millimeter-wave (mm-wave) frequency range (typically defined as 30–300 GHz). Prime target applications of silicon mm...
متن کاملHybrid SiC Power Module with Low Power Loss
Mitsubishi Electric has developed a 1.7 kV hybrid SiC power module consisting of 6th generation Si-IGBT and SiC Schottky Barrier Diode (SBD). Adopting SiC-SBD enables a significant power loss reduction during the diode turn-off and IGBT turn-on. And adopting of 6th generation IGBT enables the reduction of the IGBT turn-off loss. By using the newly developed chip set, high temperature enduring g...

متن کاملSpatial Power Combining for
s the operating frequency of semiconductor solidstate devices increases into the millimeterwave region, the size of the devices and their power handling capability are reduced. In order to provide the advantages of a solid-state technology for moderate power levels at millimeter-wave frequencies, solid-state components must be combined. Spatial power combining provides enhanced RF efficiency by...
متن کاملSpatial filters for high-peak-power multistage laser amplifiers.
We describe spatial filters used in a Nd:glass laser with an output pulse energy up to 300 J and a pulse duration of 1 ns. This laser is designed for pumping of a chirped-pulse optical parametric amplifier. We present data required to choose the shape and diameter of a spatial filter lens, taking into account aberrations caused by spherical surfaces. Calculation of the optimal pinhole diameter ...
