Abstract[English]
The invention relates to a traveling wave parametric amplifier (TWPA) for amplifying a target signal. The TWPA comprises a nonlinear transmission line (T1, T2) for receiving and propagating the target signal. The TWPA also comprises a plurality of coupling elements (DC1, DC2), wherein the plurality of coupling elements (DC1, DC2) are arranged at a distance from one another along the nonlinear transmission line (T1, T2). Each coupling element of the plurality of coupling elements (DC1, DC2) is configured to couple a pump signal portion from a pump feed line (D1) into the nonlinear transmission line (T1, T2), wherein the coupled-in pump signal portions form a total pump signal co-propagating in the nonlinear transmission line (T1, T2) in the same direction as the target signal for amplifying the target signal.[French]
L'invention concerne un amplificateur paramétrique à ondes progressives (TWPA) pour amplifier un signal cible. Le TWPA comprend une ligne de transmission non linéaire (T1, T2) pour recevoir et propager le signal cible. Le TWPA comprend également une pluralité d'éléments de couplage (DC1, DC2), la pluralité d'éléments de couplage (DC1, DC2) étant disposés à une certaine distance les uns des autres sur la ligne de transmission non linéaire (T1, T2). Chaque élément de couplage de la pluralité d'éléments de couplage (DC1, DC2) est configuré pour coupler une partie de signal de pompe d'une ligne d'alimentation de pompe (D1) dans la ligne de transmission non linéaire (T1, T2), les parties de signal de pompe couplées formant un signal de pompe total co-se propageant dans la ligne de transmission non linéaire (T1, T2) dans la même direction que le signal cible pour amplifier le signal cible.
