I downloaded ADRF6620 S-parameters files from the website and, there are two s2p files.
Does "MIXEROUTPUT_deembeded.s2p" file data measure from RF input to Mixer output?
Could you let me know more detail about measurement condition?
I think it might be RF IN to Mixer output data (and baluns losses are de-embedded). Reference resistance is 75 ohm. Am I correct?
The background is I'd like to know the power gain value instead of voltage gain from RF INPUT to MIXER OUTPUT.
Data sheet stated voltage conversion Gain is -2dB (@fIF = 200MHz, fRF = 900MHz).
My customer's measured value was around -5dB at power gain. (Including the Balun loss at the evaluation board)
I saw that S-parameter file data it stated at S21 (around 200MHz) is -4.6dB at MAG. Looks like closely results.
