A two-stage power amplifier (PA) using GaN HEMTs is presented with a high power added efficiency (PAE) and good linearity. This PA employs a structure of a class-C PA driving a class-AB PA to obtain a ...

This study attempts to study the two-phase immersion cooling for the FOCoS HPC package subject to a power input of up to 1000 W which hasn’t been reached before. It explores two approaches: an ...
