Hi there!
Objective: To design a wideband matching transformer to match a 10 Ω load to a 50 Ω transmission line at a center frequency of 1.0 GHz, matched so that |Γin| < 5%.
Q. Using N = 4 section (Equal Ripple) Chebyshev matching transformer.
I think I did everything correct, BUT I get a negative width at the end.
What does negative width mean? Widths cannot be negative!
Below is my attached attempt!
Note: I used impedance calculator from: https://www.mantaro.com/resources/impedance-calculator.htm
Thanks

- Calculate the Scaling Constant, A.
- Calculate all partial reflection coefficients.
- Calculate the characteristic impedances.
- Calculate the widths & lengths for using micro-stripline sections. trace thickness, t = 1.4 mm, PCB thickness, h = 4.7 mm & ϵr = 4.2.
