Abstract: When linear power amplifiers are driven into or beyond the 1-dB compression point for power efficiency purposes, they will produce undesirable Inter-Modulation Distortion (IMD). The powerful and versatile HP Microwave Design System (MDS) does not allow one to use alternative search or adaptive algorithms to compare their performances in speed, robustness, and complexities. For the first time (to the best of the authors' knowledge), this paper reports on the novel technique, the Sequential Algorithms Technique (SAT), to enable the MDS analysis of circuits using user-designed optimization routines. It is made possible with the new ability to execute analysis actions sequentially by using an integrated system of Symbolically Defined Devices (SDD) and Frequency-Domain Defined Devices (FDD). This new technique will be verified against MDS by investigating an adaptive predistorter circuit.
