Title: lna design at 5ghz microwave office
Post by engineer on Jun 16^th, 2011, 12:08am

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
