摘要
Disclosed are an electronic impedance tuning apparatus for measuring a load-pull of a mobile amplifier and an electronic impedance tuning method therefor. An electronic impedance tuning apparatus according to one embodiment of the present invention comprises: a coupler for transferring, to transmission lines respectively connected to a through port and a coupled port, an input voltage inputted to an input port; a magnitude part for controlling a change in the magnitude of the impedance through a change in length difference of the transmission lines; and a phase part for controlling a change in the phase of the impedance through an equal length change of the transmission lines.
