Abstract
(EN)
The present invention relates to a mixer and, more specifically, to a mixer for an RF receiver, which can reduce glitches resulting from the LO feedthrough effect. The mixer for an RF receiver is a single balanced mixer for an RF receiver, and comprises: an input terminal to which an RF signal is input; a plurality of switches which are connected in parallel to the input terminal; left dummy switches connected to the one ends of the switches; and right dummy switches connected to the other ends of the switches.

La présente invention concerne un mélangeur et, plus particulièrement, un mélangeur pour un récepteur RF, qui peut réduire les pics résultant de l'effet de traversée de l'OL. Le mélangeur pour un récepteur RF est un mélangeur équilibré unique pour un récepteur RF, et comprend: une borne d'entrée dans laquelle un signal RF est injecté; une pluralité de commutateurs qui sont connectés en parallèle à la borne d'entrée; des commutateurs factices gauches connectés aux extrémités des commutateurs; et des commutateurs factices droits connectés aux autres extrémités des commutateurs.
