Some questions to speed up my learning period: 1) I have a circuit (a 15 branch power splitter) and I want to perform and optimization varing fifteen microstrip length at the same time in the some amount. I can set L=?70 branch by branch, is this the only one way?. How do I do to assure L,TL1=L,TL2=...=L,TL15. Is it possible to define the length as a variable rather than a nummber preceded by a " ? ". 2) I've seen the program is able to get pretty good component values (when optimizing), nevertheless the values sometimes go beyond practical limits (it's typical to get very long lines when I pretend to minimice VSWR, losses are very good to get 1:1 ;-). HOW CAN I limit the range of values a component can take when optimizing?.
