    Hello,

    I am simulating a lna at 5ghz.
    I have 2 questions here.

    Firstly, while importing s-parameter data file for a HEMT transistor, the S-param data is from 100mhz - 20 ghz and noise data

    is from 2 - 18 ghz? why ? Because while simulating it gives the message like illegal noise parameters.

    Secondly, here to stabilize the amplifer, I have used resistive loading, but a TLIN is added to the shunt resistor in AWR MWO

    ? why is a TLIN added ?

    Please explain.

    Cheers
