About the device S-parameters files
To whom it may concern:FormerMemberlallisonanalog-adminstevebjobo23
We are going to design some PAs, using HMC383LC4,HMC498LC4,HMC1040LP3CE,HMC1016.
These S-parameters on theirs websites are avalable.
I want to know:
If these S-parameters are measured form theirs evaluation boards( which means the reference planes are the K connectors) or if these S-parameters have been deembedded ( which means the reference planes are the chip pins) .
Waitting for your response and thank you very much.
Unless otherwise specified on the s2p filename or in the comment section at the top of the s2p file itself, s-parameters for RF amplifiers are not de-embedded, they represent the performance of the populated evaluation boards.
Thank you for your fast response to my questions:
I still have some questions in details. About the four devices(HMC383LC4,HMC498LC4,HMC1040LP3CE,HMC1016)'s S-parameters:
S-parameter file's name: "HMC383LC4 deembedded.s2p"
Details in the comment section of this file:"Vdd = +5V, data includes two Southwest connectors, Room "
----So I suppposed that maybe this S-parameter represent the performance of the populated evaluation boards. But the file name is wrong.
Details in the comment section of this file:"!Misc: Vdd1,2,3 = 5 V, Idd = 250 mA, data includes two Southwest (K) connectors, Room "
---So I suppposed that this represent the evaluation board.
Details in the comment section: none of related comment
---Because it is packaged device, so I suppposed that this represent the evaluation board.
Details in the comment section: "NO DE_EMBEDDING WAS DONE. Data was collected using an calibrated network analyzer. The reference plane is the microstrip launcher."
---This represent the evaluation board.
Are these above-mentioned judgments reasonable?
Thank you very much for your help and waitting for you response again.
Wish you have a good day!
