How to correctly establish S parameter simulation schematic of ADL5523 in the ADS?


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!:(
