Abstract
The S-parameters of a transistor are measured at a plurality of bias points, and using a tentatively decided load resistance value, the S-parameters on the load curve are examined, based on which the power gain and input/output power characteristics are obtained to determine the optimum load. Then, by using a linear simulator, input and output circuits are designed so that the optimum load can be realized.
