Abstract: We designed and fabricated a compact and low-cost ultrabroadband amplifier module. The 3-dB-down-cutoff frequency (f3dB) of the module is 108 GHz with direct-current (dc) block functions.

Energy innovation trends such as sustainable grids, and the electrification of the consumer transportation market are accelerating the adoption of medium-voltage (MV) silicon-carbide (SiC) technology.
