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
