LTC2107 analog input balun design and simulation

Category: Hardware
Product Number: LTC2107

Hello,

I am designing a product that will use LTC2107 and will have an analog input in the range of 30-90MHz.

I would like to use diffrent transformers from the ones noted at the datasheets app notes/ the eval board schematics

How can i simulate the effect of diffrent transformers on the performance of the ADC?

Is it just a matter of performing an S21 simulation on ADS using 50 ohm terminal and a costume impednce diffrential terminal?

If it is, where can i find a model of the input impednce of the LTC2107?

thank you :)

p.s

one of the transformers used in the datasheet is not stocked. both transformers used in the eval board are stocked but it says its for 5-70MHz, how bad will it be for 30-90MHz?

Edit Notes

I added the P.S
