Title
(EN) HARMONIC REJECTION MIXER ARRANGEMENT
(FR) AGENCEMENT DE MÉLANGEURS À RÉJECTION D'HARMONIQUES
Abstract
(EN)
It is disclosed a mixer arrangement for complex signal mixing comprising a first harmonic rejection mixer, and a second harmonic rejection mixer. Each of the harmonic rejection mixers comprises mixer unit cells wherein each mixer unit cell comprises a differential input, transconductance elements corresponding to the differential input, and a switching network arranged to switch signals from the transconductance elements to a differential output, and the first and the second harmonic rejection mixers have mutual quadrature phase relationship. The first and the second rejection mixer share a plurality of mixer unit cell, each comprising an input for receiving a signal to be mixed, an input for receiving control signals derived from a local oscillator signal, and one output for each of the first and second harmonic rejection mixers. A radio circuit comprising such a mixer arrangement and a communication apparatus comprising such a radio circuit are also disclosed.

L'invention concerne un agencement de mélangeurs pour le mélange de signaux complexes, comprenant un premier mélangeur à réjection d'harmoniques et un second mélangeur à réjection d'harmoniques. Chacun des mélangeurs à réjection d'harmoniques comprend des cellules d'unité de mélange, chacune des cellules d'unité comprenant une entrée différentielle, des éléments à transconductance correspondant à l'entrée différentielle et un réseau de commutation agencé pour commuter des signaux entre les éléments à transconductance et une sortie différentielle, et les premier et second mélangeurs à réjection d'harmoniques ont une relation de quadrature de phase mutuelle. Le premier et le second mélangeur à réjection d'harmoniques partagent une pluralité de cellules d'unité de mélange, chacune comprenant une entrée pour recevoir un signal à mélanger, une entrée pour recevoir des signaux de commande dérivés d'un signal d'oscillateur local et une sortie pour chacun des premier et second mélangeurs à réjection d'harmoniques. L'invention concerne en outre un circuit radio comprenant un tel agencement de mélangeurs et un appareil de communication comprenant un tel circuit radio.
