I am trying to make Design Kit (only schematic) with a simple resistor in its palette. But that resistor value should change with frequency, when S parameter simulation is done. Design Kit manual shows how to create a resistor, but how to add this frequency functionality in that resistor. Would I have to create a new parameter called frequency in it or model file(.net) would be used to add this functionality.
Can anyone point me in the direction. Please ask if my question was not clear.
Thankyou for the answer Toby, I'll look into it, but you say that resistance is treated as constant. But when S- Parameter simulation is performed for the sample resistor that is designed in tutorial in Design Kit Manual, the resistance value clearly changes by few decimal places with frequency. (Although this is subcircuit model not just a simple resistor but and inductor and capacitor connecte to it, which is shown in its model file).
There is a demo workspace provided by ADS to test that resistor which is available in .../examples/design kit/samplekit/examples/SampleKit_Demo_wrk.
I am uploading its pictures.
Just use an equation-based 1-port. If it's just a function of frequency, use a linear one. Variable freq is predefined in any sort of frequency domain simulation (HB and alike evaluate multiple time for different freq values ... harmonic tones. No need to take care)
There are flavours for specifing Z or S . Just consult the help. Everything is well documented.
Btw, primitive elements like R, L, C cannot be used as they are treated as constant and aren't reevaluated for different freq values.
Have fun!
