wilkinson hybrid
I am going to simulation Wilkinson hybrid use ADS2004A.
Now,i have a problem. I don't know how to setup TFR (Thin Film Resistor) .
In A DS help,
"Rs = sheet resistivity, in ohms/square.
2. If Freq is set to a value other than zero, then Rs is scaled with frequency as follows:
Rs (f) = Rs (Freq) (f/Freq) (for microstrip)
If Freq=0, then Rs is constant with respect to frequency. Setting Freq=0 is correct in most cases. "
how to comprehend this expressions and how to calculate Rs?
Who have this article "E. Hammerstad and O. Jensen, "Accurate Models for Microstrip Computer-Aided Design," MTT Symposium Digest, 1980, pp. 407-409"?
If you have it or you konw any site that i can download this article.
please tell me.
Thanks you very much!
