STL CAlculator

Enter data: R1 and R2 where R2 > R1, Characteristic Impedances (Zoa and Zob) and Velocity Factors (VFa and Vfb) for transmission lines TLa and TLb, and Frequency (MHz).

Then click Calculate button.

La/Wavelength and Lb/Wavelength are fractional wavelengths of ideal transmission lines (Vfa = VFb = 1). Physical Lengths include Velocity Factors entered above.
