WebSep 12, 2024 · Note that β1 = 2π / λ, where λ is the wavelength of the signal in the transmission line. Therefore l1 = β1l1 β1 = β1l1 2π λ ≅ 0.126λ. The length of the second section of the transmission line, being a quarter-wavelength transformer, should be l2 = 0.25λ. Using Equation 3.19.3, the characteristic impedance Z02 of this section of ... WebKey Takeaways. An impedance mismatch in a circuit or along a transmission line will produce a reflection back to the source of the signal. When a signal reflects, the power transferred downstream towards a load is reduced. Impedance matching provides a dual role of enabling power transfer into a load by suppressing reflections.
