POWER MANAGEMENT METHOD FOR A LOW-NOISE AMPLIFIER IN A CHANNEL FOR RECEIVING ELECTROMAGNETIC SIGNALS, AND A RECEIVING CHANNEL IMPLEMENTING SUCH A METHOD

摘要

The present invention relates to a method for managing the power use of electronic components in a channel for receiving electromagnetic pulse signals. Said invention also relates to a receiving channel implementing such a method. The invention is particularly of use for low-noise amplifiers and for the various electronic receiving units of radar listening systems. The low-noise amplifier (10) operates with a power supply voltage and a polarization current. Said power supply voltage and/or said current are controlled based on the amplitude of each received signal. Control (1, 2) is carried out based on the measurement of said amplitude.
