Fast simplified real frequency technique (FSRFT)is a numerical solver used to solve microwave broadband double-matching (DM)circuit design problems in a much faster and effective manner. Recently, it hasbeen reported that an FSRFT based Matlab code can complete the design of a orderlowpass lumped element double matching network to match a given generator andload impedance within an optimization time of only 0.6 seconds, a 47 fold less timethan that of the same design done using the classical simplified real frequencytechnique (SRFT). FSRFT owes this superior speed performance to the fact thatit tracks only (systemunknowns plus 1) numberof passband extremum points selected from among the number ofgain data (). This work introduces a simple numericaltechnique called PED (passband extremums determination technique) to be used indetermination of these passband extremum points (PEs). An exemplary order microwavebandpass DM circuit design using FSRFT based Matlab (of Mathworks Inc.) codeand the simulation of this design via MWO (of AWR Corp.) has yielded the samecircuit performance with an exact agreement. Thus, FSRFT, equipped with the PED,newly proposed hereby, might be used as a powerful solver in designingbroadband circuits in many fields such as RF/microwave, radar, and communications.
