  • Abstract
    A new technique for the design of a microwave GaAs MESFET amplifier under large-signal conditions with the best compromise between output power and third-order intermodulation (IM3) distortion is described. It is based on the device nonlinear model which is used with the Volterra series to predict the large signal behaviour. Experimental verification is given for two MESFET X-band amplifiers with various load. conditions and the results compared with the theory.
