This are problems from Book Microwave Engineering By David Pozar.
I am preparing for an exam based on this subject and stuck with some part of it.
Problem 8.
I calculated ouput reflection coefficent as = 0.85L71(degrees).
I am getting the length of OC Stub to be 0.204(wavelength) and series stub to be 0.203(wavelength).
But in solution its given to be
length of OC Stub to be 0.298(wavelength) and series stub to be 0.107(wavelength).
Here is the link of my solved smith chart solution
Since there multiple correct answers as it depends on the way traveled on smith chart, is my answer correct?
Secondly I have googled for many links which shows impedence matching using lumped elements, but didnt find a single one which shows the same with only impedance chart can any one help me with the designing steps of matched lumped elements using only Z-Smith chart.
In the above book,its given when the impedence lies in 1+jb circle but not when it doesnot lie outside 1+jb circle.
I donot understand how to travel on the same impedence using z-chart only.
It would be also very helpful if there are links which have java applets which can solve any sums based on rf circuits atleast theoritically.
-Thank you.
