    Abstract

    A cascode class-E power amplifier (PA) operating at 5.2 GHz has been designed using Advanced Design System simulation. RF circuit performances such as output power and power-added efficiency before and after RF stress have been experimentally investigated. The measured output power, power-added efficiency, and linearity after high-input-power RF stress at elevated supply voltage show significant circuit degradations. The impact of hot-carrier injection and gate oxide soft breakdown on cascode class-E PA reliability is discussed.
