BTW the original question never changed. Just lots of non-answers. If the NF depends on freq, and the freq .vs. NF data is available in a table in the datasheet, I have not been able to determine if/how that data can be incorporated into a cascade analysis sweeping frequency.
Can you be more specific? How is the IIP3 vs. freq table input into AWR/ADS? Is is a file of some format, or entered into GUI? If it is via GUI can you send screenshot? Or is there a manual showing this?
I'm not sure what you mean my "frequency selection". My end result I want is graph showing...
As I mentioned, I have the data. For example the TQP369185 provides s-param file for gains, and its datasheet provides tables of IIP3 and NF vs. freq.
I have looked at ADISIMRF and it seems very limited. If your entire chain consists of ADI parts then it is easy, but how would I provide the...
I wrote python script that allows me to navigate to an s-parameter file; specify frequency, row, and column; then it extracts value via interpolation; converts it to dB, then puts it in buffer so I can then just CTRL^V value into speadsheet cell. Makes it easy to populate gain values into...
Spreadsheet is what I am using now (along with some Python helper scripts). I just keep seeing advertisements for expensive tools (Matlab, Simulink) which claim to do more than spreadsheet.
I don't want to invest $ and find out that they actually do less.
Maybe I'm not conveying question clearly.
I would like to sweep an RF chain for gain, IIP3, noise figure vs. freq.
I can obviously use s-parameters to define gain as a function of frequency.
However, Is there a mechanism for specifying IIP3 and noise figure as functions of freq?
For example...
Anyone know how, in either Matlab, or Matlab+Simulink, to do cascade analysis of RF chain when IIP3 and noise figure of some components is a function of frequency?
