Bramham Transformer Calculator

This will calculate the exact (approx. 12th wave) wavelengths for a Bramham impedance matching transformer.
The short sections of Z2 and Z1 provide the transformation of input line Z1 to output line Z2.

Wavelength

Note* Implementation is approximately 2/3 the size of a quarter wave transformer.
Note* Has slightly lower bandwidth than a quarter wave transmformer.
Note* Include velocity factor of transmission lines in any real length implementation.
