Step 1

A quarter wave transformer is a transmission line and its length is equal to one-fourth of wavelength. It is a matching device, used between a transmission line and a load impedance. If Zo is the characteristic impedance of a transmission line and if ZL is the value of the load impedance, then the value of the characteristic impedance of the quarter wave transformer can be expressed as
