Hello,
Our lab prepare to use ADL5523 to improve the performance fo existing circuits. it works at 433MHz. I have downloaded the ADL5523 s3p file in official website. It is different from s2p, and it use port2(VPOS/VBIAS)to match output impedance. i can't figure out it.
So I'm wondering how to establish a correct simulation eschematic for ADL5523 to match the input and output impedance！:(
thanks!

Hi Vivien,
Yes the file of the format is a bit different than the typical format. You can see the details on the comment section,
! RF in - port 1! bias - port 2! RF Out - port 3
So you need to assume port 3 as the output of the amp. As an example the gain will be s31 instead of s21. Or you can open the file in spreadsheet and delete the data for port 2 completely.
The bias port is also include to show the suppression performance of the bias path.
Best,
Kagan
