Abstract :Fast simplified real frequency technique insert ignore into journalissuearticles values(FSRFT); is a numerical solver used to solve microwave broadband double-matching insert ignore into journalissuearticles values(DM); circuit design problems in a much faster and effective manner. Recently, it has been reported that an FSRFT based Matlab code can complete the design of a  order lowpass lumped element double matching network to match a given generator and load impedance within an optimization time of only 0.6 seconds, a 47 fold less time than that of the same design done using the classical simplified real frequency technique insert ignore into journalissuearticles values(SRFT);. FSRFT owes this superior speed performance to the fact that it tracks only  insert ignore into journalissuearticles values(system unknowns  plus 1); number of passband extremum points selected from among the  number of gain data insert ignore into journalissuearticles values( );. This work introduces a simple numerical technique called PED insert ignore into journalissuearticles values(passband extremums determination technique); to be used in determination of these passband extremum points insert ignore into journalissuearticles values(PEs);. An exemplary  order microwave bandpass DM circuit design using FSRFT based Matlab insert ignore into journalissuearticles values(of Mathworks Inc.); code and the simulation of this design via MWO insert ignore into journalissuearticles values(of AWR Corp.); has yielded the same circuit performance with an exact agreement. Thus, FSRFT, equipped with the PED, newly proposed hereby, might be used as a powerful solver in designing broadband circuits in many fields such as RF/microwave, radar, and communications.
