Title
(EN) AN ELECTRONIC POWER DIVIDER FOR RF-SIGNALS AND ELECTRONIC RF-SIGNAL TRANSCEIVER SYSTEM COMPRISING SUCH DEVICE
(FR) DIVISEUR DE PUISSANCE ÉLECTRONIQUE POUR SIGNAUX RF ET SYSTÈME ÉMETTEUR-RÉCEPTEUR DE SIGNAL RF ÉLECTRONIQUE COMPRENANT CE DISPOSITIF
Abstract
(EN)
The invention is an electronic power divider (1) for radio frequency signals, comprising one or more inputs (IN1,..., IN4) designed to be fed by an electromagnetic radio frequency signal (S) with predetermined wavelength (λ); at least two outputs (OUT1....,OUT12) for the signal (S), each one of which is connected to the same input (IN1,...,IN4); respective electric paths (3) suited to connect each output (OUT1,..., OUT12) to the corresponding input (IN1,..., IN4) and means (7) for the selective variation of the electric impedance (Z) associated with each one of the electric paths (3) during the passage of the signal (S) through the latter. The impedance variation means (7) are respectively suited to vary the impedance associated with the paths (3) in a discrete manner between two predetermined values, respectively a lower value (ZMIN) and an upper value (ZMAX), and to simultaneously maintain the value of the impedance associated with two or more paths (3) at least at the lower value (ZMIN). An electronic system for transmitting and receiving an electromagnetic signal (S) comprising such electronic power divider (1 ).

L'invention concerne un diviseur de puissance électronique (1) destiné à des signaux radiofréquence, comprenant une ou plusieurs entrées (IN1,..., IN4) destinées à être alimentées par un signal radiofréquence (S) électromagnétique de longueur d'onde prédéterminée (λ) ; au moins deux sorties (OUT1....,OUT12) destinées au signal (S), chacune étant connectée à la même entrée (IN1,...,IN4) ; des trajets électriques respectifs (3) appropriés pour connecter chaque sortie (OUT1,..., OUT12) à l'entrée correspondante (IN1,..., IN4) et des moyens (7) destinés à la variation sélective de l'impédance électrique (Z) associée à chacun des trajets électriques (3) lors du passage du signal (S) à travers ces derniers. Les moyens de variation d'impédance (7) sont respectivement appropriés pour faire varier l'impédance associée aux trajets (3) d'une manière distincte entre deux valeurs prédéterminées, respectivement une valeur inférieure (ZMIN) et une valeur supérieure (ZMAX), et pour maintenir simultanément la valeur de l'impédance associée à au moins deux trajets (3) au moins à la valeur inférieure (ZMIN). L'invention concerne également un système électronique permettant d'émettre et de recevoir un signal électromagnétique (S) comprenant ce diviseur de puissance électronique.
