Pancho, Didac, thank you for your responses.
Here are my comments.
Quote:This answer might be out of interest you are faceing.
I think your problem is how to treat s-parameter model in time domain circuits such as E-class ampilifier.
If so. you have to rely on convolution or linear macro approximation.
Yes, it's true. But I didn't understand what you mean under convolution. What I should convolve?
Quote:For example, Cadence Spectre's Nport support both methods.
I saw description of Nport. In my Spectre manual there is no description of format of file that contains S-parameters.
What is - series of lines that start with some frequency and followed by S-parameters, separated by commas.
There is also no mention on characteristic resistance. 50 Ohm or something else?
If I understood in proper way your hint, Spectre instantly evaluates impedance of node and recalculate S-parameters (that originally were specified for 50 Ohm) ?
Quote:in your case for your frequency the frontier between induced fields and radiated fields is around 3'5m so for antennas separated around 30-40m
The operational distance is 5-10cm.
Quote:So I think that you can model the antenna just as a load for the receiver and other load for the transmiter,avoiding potential problems mixing time domain simulation with frequency domain data.
In our concept system start is of critical importance. If no designed properly system may cannot start.
So precise transition simulation is the must. More it's precise, less probability of fault.
For this reason I'm looking for approach that would be as much close to reality as possible.
Thank you one more time for you assistance.
Regards.
Pavel.
