complex impedance calculator
Hi,
I found out how I can calculate the complex impedance of a unkown load by replacing it with two other loads and doing some maths, but what I´m really looking for is to calculate the complex impedance of a load by measuring forward and reflected power right after the power amplifier. I remember these formulas were taught at university; how to calculate the complex impedance from 3 different measurements of forward and reflected power, but I can´t find the maths in my books, neither on the internet. Or is there an IC available that does all the complex impedance calculation by itself?
Can anyone help me out on this one?
Thanks a lot on forehand.
