Abstract
A method and circuit for evaluating a charge impedance at the output of a directional coupling having a first line adapted to convey a desired signal between a first terminal and a second terminal adapted to be connected to an antenna, and having a second line coupled to the first one including a third terminal on the side of the first terminal and a fourth terminal on the side of the second terminal, wherein the signal present on the fourth terminal is submitted to a homodyne detector having its local oscillator signal sampled from the third terminal.
