Desing amplifier in ADS(S-parameters)

Help to understand please with the following problem:
It is necessary to develop LNA on 2,3-2,4 GHz with NF <1 dB.
There are S-parameters on the transistor (NE3510M04):
1. How them to add in ADS? (I only start to master it).
2. How to specify on S-parameters Stability Factor or s-parameters are already resulted for a stable operating mode of the transistor?
In advance thanks.

Hi, there!

It is not necessary to add the S-parameters to the schematic in ADS. Besides, you are limited to employed the S-parameters provided by the manufacturer, in this case NEC, since these are obtained at certain Ic and VCE. If you use the Non-linear model of teh element (generaly, provided at the end of the datasheets), you can obtain the parameters at any bias point you decide. With this results, you can stablish your gain and noise circles in teh results page and select the better choice for your requirements.

hi, please follow the ADS DesignGuide about LNA. You could get your answer.

Recently, I am also a new hand on PA design. NEC NE5531079A is used in my design. I followed the DesignGuide about PA in the ADS. But the resource prepared by NEC is so little. It is very difficult to use NEC's product.
