Dear all,
I'm trying to optimize the impedance matching network in the attached simulation, using the optimization tool of ADS. The goal is set to be dB(S(1,1))
Hmm, do you know the transfer function, H(s), for your filter? There is a Filter Design program that may help.
Match-n-freq™, a Matched-Filter (Transfer Function ... Poles/Zeroes) Design Application
-------------
Match-n-freq™ is a (free) Pulse Shaping Filter program that finds the pole-zero locations of a transfer function, H(s), for a matched-filter design. H(s) equals a -desired- signal (Yout) divided by a given input signal (Yin). Both Yout and Yin are functions of frequency. Download at http://fortranCalculus.info/apps/match-n-freq.html .
H(s) has equal sidelobe peak amplitudes in a Bode plot; i.e., Peak i = Peak j for all i, j.
Group delay may also be calculated to compliment a given data set, thus, providing a flat group delay. Minimizing Intersymbol Interference in a read/write channel for disc drives by shaping and slimming an isolated readback pulse was the main objective for writing this program.
Make your own 'transfer function' app: have a function you want to try? See the Match-n-freq's source code (included in FC-Compiler-install.exe) ... FC-Compiler\demos\nesting\filter.* files. Modify these transfer function to fit your desired function(s). Download the free FC-Compiler™ that you will need to re-compile your version of your 'Match-n-freq' program.

Converting a pole/zero locations into a circuit solution is a touchy problem. SYNTH (?) program is what we used in the 1980s.
