I came across the
following slide on power combiner circuit and I have questions about it.
1. Why traverse across the upper half circle ? In other words, why is Zin located at the right side of Zout ?
2. Why when translating an impedance towards the generator we move clockwise around the chart ?
3. Why "ZT-line is the geometric mean of Zout and Zin." ?
4. Why overlay the Smith chart scaled for ZT on top of the Z0 Smith chart ?
5. Why is L=λ/4 located directly opposite to L=0 ?
