32+ Transmission Line Transformer Calculator Pics. Wavelength, degrees, feet in the screen shot below, we want to make a transmission line 1/8 (0.125) wavelength long, using 50 ohm line with a velocity factor of 0.78, and operating at a frequency of 7.0 mhz. To calculate the quarter wave length of a certain transmission line with a known velocity factor and frequency you may use this calculator.

Impedance Transformation Transmission Lines Electronics Textbook from www.allaboutcircuits.com

For the length in feet, this is (245.9/frequency in mhz) * velocity. As the name suggests, the length of this transmission line if fixed at a quarter of the wavelength (/4). How big is a conventional transmission line transformer?

Series section line transformer (analytic solution) for impedance matching length conversion:

How to calculate the length of a transmission line? Even if you find the line you want on the list, verify the impedance and velocity factor, since they are the important parameters. Acrastyle.co.uk) this is referred to as relay coordination. The transformer calculator uses the following formulas:
