Hi there!
I need to design an amplifier using ATF-36163 transistor. I also have to use Ansoft Design (I have not really get the hand of using this yet).
The amplifier is to operate at 5Ghz (that's the only requirement in terms of variables). I already have the S parameters in hand. However, I am quite lost on how to start. I have looked at the Gonzalez book as well.
Among the first step that I am required to do is to have one attenuator at the output to stabilize the amplifier. Therefore I have to determine the required gain and matching resistor of th attenuator.
From the Gonzalez book, I understood that using the S-parameters at 5Ghz, I should calculate the stability circle to ensure that it lies outside the smith chart. And I should follow this with calculating the Rollet's stability factor.
Am I on the right track?
Thank you
