A wideband 0.9–2.4 GHz 25 W high‐efficiency Gallium Nitride radio frequency power amplifier
In this work, a 0.9–2.4 GHz, 25 W output power, radio frequency (RF) power amplifier based on Class‐E switchmode topology has been analyzed. A load‐pull simulation method is used to optimize the power performance in the operating band.

ABSTRACT Background Patients with chronic kidney disease undergoing hemodialysis commonly experience reduced physical function, fatigue, poor sleep quality, and impaired health‐related quality of life. Intradialytic exercise has been proposed as a non‐pharmacological strategy to improve these outcomes.
