ads active filter

I made an active op amp low pass filter design in Genesys and exported the design to ADS. When using the design in ADS the filter passband and stopband look like in original design but the insertion loss is more than 240 dB. Has anyone faced this before?
I tried to change the port impedances but did not get the same results as in Genesys. Filter loss in Genesys was -6 dB. Genesys port impedances were 100e-12 ohms at the input and 1e12 ohms at the output (tried the same in ADS but no help).

Help would be needed.

Hi,

I tried some time to design in Genesys Active LowPassFilter,
Unfortunately eagleware can't design this one!
Trule i did not try to built it in ADS but Pspice make it perfectly!

OK. Basically the response is OK, the only thing bothering me is the insertion loss level shift so much down. Have to ask the supplier.
