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 anywhere close to the truth.

schematic

simulate this circuit – Schematic created using CircuitLab

I'm wondering if I can consider the schematic in parts, or if I'm forced to consider all components at the same time, and if there are some shenanigans (like transformations) that I need to perform first.

  • \$\begingroup\$ I'm not sure if you already know this or not, but a transmission line segment with a given Z0 is not the same as a resistor with resistance Z0. Sorry our schematic tool doesn't include a transmission line object, so you might need to use a better drawing tool to diagram this circuit. \$\endgroup\$ – The Photon Feb 12 at 21:40
  • \$\begingroup\$ Yeah, I only used resistor since there was no impedance component, I just hoped to make it as clear as possible by using the value as "Zn" instead of an actual resistance \$\endgroup\$ – Grak Feb 13 at 7:58

Is this what are you trying to get?

You may consider using Qucs. It includes a transmission line component.
