TRF3705: de-embedded s-parameters

Part Number: TRF3705

Hi Team,

One of my colleagues is looking for the de-embedded S-parameters for the TRF3705. I found this post:  but it doesn't seem to match this app note:

Do they need to be de-embedded?

Also, was the gain set to high or low on the modulator?

Thanks!  

Nate

    Nate:

    I did not study it but I think the S-parameter files from the previous post are the ones used in the App Note.  The App Note focuses on matching techniques for frequencies that are on the edge or just outside the designed frequency band of the internal balun.  The parameters are de-embedded to the device but likely include PCB board effects of the soldered down device.  The data is with low gain but should not be impacted by high gain as the gain circuit is in the baseband area and not the RF output.
