Title: Guy Lesthievent: Innovator in Electronic Component Calibration
Introduction
Guy Lesthievent is a notable inventor based in Villate, France. He has made significant contributions to the field of electronic components, holding a total of 3 patents. His work primarily focuses on methods for improving the performance and reliability of electronic devices.
Latest Patents
Lesthievent's latest patents include a method for calibrating a linearizer and linearized electronic component. This method involves predistortion of a signal upstream of an electronic component to compensate for nonlinear distortion. The process includes determining predistortion setting parameters by applying a bifrequency test signal to the component and measuring the relative amplitudes of the output lines. A variable indicative of the magnitude |Kp| of the AM/PM conversion coefficient is calculated based on these measurements, and the parameters are adjusted to minimize |Kp|. This method can be implemented in linearized amplifier devices and amplifier test benches.
Another significant patent is a method and device for eliminating interference signals in a direct sequence spread spectrum link. This method involves frequency detection of interference signals by comparing the spectrum of the composite input signal with a threshold. The composite input signal is then filtered using a finite impulse response filter through rapid convolution. The detection threshold is automatically controlled by estimating the spectral input density after eliminating large interference signals.
