  • Abstract
    Highly efficient GaAs power MESFETs with n+-asymmetrical lightly doped drain (LDD) structure and refractory gate metal have been developed. The excellent RF performance of 32.5 dBm output power and 70% power-added efficiency at 950 MHz, Vds=4.7 V and 21 dBm input power was typically obtained.
