Abstract
(EN)
The purpose of the present invention is to provide a low-noise amplifier equipped with notch filtering, wherein, in the low-noise amplifier comprising a degeneration inductor, a resonant frequency of the inductor and a notch filter frequency which are used for impedance matching match each other, such that the harmonic control scope of a harmonic rejection mixer can be eased.

Le but de la présente invention est de fournir un amplificateur à faible bruit équipé d'un filtrage coupe-bande. Dans l'amplificateur à faible bruit comprenant une bobine d'induction de contre-réaction, une fréquence de résonance de l'inducteur et une fréquence de filtre coupe-bande qui sont utilisées pour une adaptation d'impédance correspondent l'une à l'autre, de telle sorte que la portée de commande d'harmoniques d'un mélangeur à réjection d'harmoniques peut être facilitée.
