ADS model Doide s-param

[Dummyeng]

Hi
I face with some problem in my project
I want to use diode s2p but idont understand how can I use it
It is the file
https://www.macom.com/products/product-detail/MADP-011029-14150T
https://cdn.macom.com/s-parameters/MADP-011029_SPar.zip
First there are some s2p with different condition for example 50ma 40V
And I think that 50 ma is for diode Forward bias and 40V is for reverse forward bias
Is it correct or not?
If it is correct I get weird answer when I simulate it in ADS
40V 50ma



It is my first question

I see the same thing with your data. Maybe they measured in SHUNT configuration?

Edit: If you look at the datasheet, it shows the diode in shunt configuration to ground indeed. It is not in series in the signal path!

thank you for ur response
i dont understand i simulate in shunt and it seems incorrect

No you misunderstand things. Just look at the datasheet and you will understand why 40V is low insertion loss and 50mA is high insertion loss (=shorted to ground)

what am I missing?
