Abstract
An automatic and iterative simulation method for adjusting linearizer parameters to achieve desired AM/AM and AM/PM characteristics is disclosed. The disclosed method includes the steps of choosing a set of linearizer parameters, modeling the performance of the linearizer circuit and the power amplifier to calculate a performance index. The performance index is compared to a threshold. The method continues to iterate until the performance index is acceptable in comparison to the threshold. When the process is completed, the linearizer parameters are output for use by the designer. The disclosed method eliminates the need to engage in trial and error methods in a laboratory when combining a linearizer and a power amplifier to produce linear output characteristics.
