  • Abstract
    Dual-gate FETs with higher output impedance have been developed for ultra-high efficiency mobile communication high power amplifiers (HPAs). These FETs have a large linear gain (22 dB) and maximum power-added efficiency (PAE) of 78%, almost twice that of single-gate FETs. They operate with a 3-V supply voltage at 1.9 GHz.
