The allowance for non-linear effects in the design of high frequency circuits has so far been relegated to the empirical domain, or has required the use of very expensive software, or software developed within certain institutions and not commercially available. Recently a low cost package (C/NL) has been released for the analysis and optimisation of non-linear microwave circuits, making use of a personal computer. In this paper the authors report on an investigation of the usefulness and reliability of this program. They have measured the S-parameters of a MESFET over the range from 1 GHz to 10 GHz, and at a variety of bias values, and have tried using C/NL and other software to fit a model to these data. In C/NL use has been made of the non-linear model thus generated to predict the gain compression, intermodulation and harmonic distortion parameters. The results have been compared with measured parameters.<>
