Abstract
A method for transforming the impedance of a radio-frequency transmission line of a printed circuit from a first impedance value to a second impedance value, the radio-frequency transmission line being adapted to transport a radio-frequency signal at a frequency value comprised in a frequency range defined between a minimum frequency value and a maximum frequency value, wherein the following steps are envisaged:—dividing the radio-frequency transmission line into a plurality of circuit sections each one of the circuit sections including a first and a second impedance connected in parallel with each other by two circuit branches placed at a maximum distance (d) from each other, wherein the circuit sections have respective third impedance values that gradually increase, respectively decrease, from the first impedance value to the second impedance value;—determining the maximum distance between the circuit branches in such a way as to avoid any undesired frequency values within the frequency range;—setting a fourth impedance value of one of the two impedances;—calculating a fifth impedance value of the other one of the two impedances, such that the impedance value of the circuit section is the third respective impedance value.
