I've been doing a lot of research on impedance matching and I am just having a hard time understanding some of the specifics and I was wondering if someone here could help me out.
I have a 50 Ohm Antenna connected to an amplifying circuit which then outputs to a 50 Ohm sma jack. As part of the amplifying circuit there is an amplifier and a combination of other components. For your reference I have the amplifying circuit below. I also have the S parameters for the amplifier.
So the sample circuit I posted is designed for a 500 MHz signal. I would like to redesign it for a 150 MHz signal.
I'm not really sure how to go about it, but my current thought is to try and get the combination of S11+Impedance(6.8 NH)+Impedance(100pF) as close to 50 ohms as possible, and the same for the output but with using S22+impedance(100pF). So I would adjust the values of these components to get the best fit.
Is this even in the ballpark of being correct?
