I'm new to Genesys and doing match for a amp in 500~700MHz band. I set the goal to -20dB for S11 and S22 but Genesys just matchs part of the band to -20dB. How can it be set to match the whole band?
In the Optimization Goal settings dialog box, use the "Min" and "Max" columns to specify the frequency band you want to match within. So in your case, you can set Min to 500 MHz and Max to 700 MHz. You can also set multiple simultaneous goals to, for example, specify an in-band goal and an out-of-band goal.
