Xavier Deplancq

Title: Xavier Deplancq: Innovator in Satellite Technology

Introduction

Xavier Deplancq is a notable inventor based in Toulouse, France. He has made significant contributions to the field of satellite technology, holding a total of 3 patents. His work focuses on methods and devices that enhance the performance of satellite payloads.

Latest Patents

One of his latest patents is a method and device for suppressing interfering signals in a satellite payload signal. This innovative method addresses the challenge of spurious signals in payload signals supplied by receiving antennas. The satellite system includes an array of measurement antennas that provide measurement signals, which are combined with the payload signal. By determining reference weighting coefficients based on the combined signals, a reference beam is formed. This beam, along with the payload signal, is then processed using anti-jamming weighting coefficients to create an anti-jammed beam.

Another significant patent by Deplancq is a method for calibrating a linearizer and linearized electronic component. This method involves predistorting a signal upstream of an electronic component to compensate for nonlinear distortion. The calibration process includes applying a bifrequency test signal to the component and measuring the relative amplitudes of the output lines. By calculating a variable indicative of the AM/PM conversion coefficient, the predistortion setting parameters can be adjusted to minimize distortion.
