Modelling Tee and Pi networks using ABCD matrix models

In this notebook I have used ABCD Networks to describe individual components in Tee and Pi circuits, to build the circuit networks and then calculate their respective Immittances:-

Notebook: two_port_nodes

This example shows a 3rd order Chebyshev filter with 80MHz cutoff, $Z_0=75\Omega$ - calculated for F=70MHz:-

UPDATES:

  • Added a spice analysis of the low pass filter to verify the results.
  • Added S-Parameter node results and diagrams
