Derivation of input admittance of a lossless T-Junction Power Divider that is matched at the input port
I'm trying to understand how the equation for the input admittance for a lossless T-Junction power divider was derived, which is only matched at the input.
Let \$Z_0\$, \$Z_1\$, \$Z_2\$ be the ...

Output from a system of cascade connection with Wilkinson's divider and Quadrature hybrid
So I have this system, with
\$f=3GHz\$
\$b = \frac{λ}{4}\$
\$a = 0<a<b\$
and I want to know the output at ports 2 and 3.
I'm wondering how exactly I should approach it, and if my sketch is ...

How to determine the frequencies in which the L&C model of an artificial transmission line works?
I want to model an artificial transmission line with L & C. So far I used the following circuit and used the values of L=400 pH and C=0.16 pF so that Z=sqrt(L/C)=50 ohms. So, expected S21 and S31 ...

How does a Wilkinson power divider achieve isolation?
Say we have a Wilkinson power divider:
The explanation I've heard about how ports 2 and 3 are isolated is this: say there's a signal generator attached to port 2. This can take two paths to port 3: ...

What happens to port isolation in a Wilkinson power divider when source impedance isn't matched?
Say we have a Wilkinson power divider:
So far as I understand it, if we say port 1 is the input, and the other ports are outputs, then the power is split evenly between the outputs.
If one of the ...
