ABSTRACT:
The present invention relates to a reception device for microwave signals, in which it is possible to extract information (V2) linearly dependent on the power level received at the input of the said device. According to the invention, the profile of the control voltage of the variable power attenuators (6, 7, 8) of the device is modified in order to obtain a curve of the control voltage which is of hyperbolic shape, and this voltage is linearized by a polynomial unit (11).
Application for the production of point-to-point links in the field of directional millimeter radio.
