In this brief, soft-switching resonant DC transformer (DCX) for the class-D switching amplifier with the symmetric bipolar outputs is proposed. The proposed DCX consists of a single transformer ...

Abstract: This letter presents a K-band power amplifier (PA) monolithic microwave integrated circuit (MMIC) with frequency reconfigurable operation in a 0.15-$\mu \text {m}$ GaN-on-SiC process. The ...
