Signal Processing Group Inc. designs, develops and manufactures analog and RF/wireless ASICs and modules

Calculation of the propagation constant of ideal transmission lines

Alpha, the attenuation ( real part of the propagation constant = 0)

Lo (Inductance/length):

Co (Capacitance/length):

f (Frequency):

e (Effective permittivity):

beta:

alpha is the attenuation ( real part ) and beta is the phase ( imaginary part) of the propagation constant
