Title
(EN) MULTIBAND RADIO RECEIVERS

Abstract
(EN) - 40 - Abstract A configurable radio frequency receiver (74) is provided. The receiver has at least one low noise amplifier (86a, 86b); an oscillator arrangement for producing a plurality of signals having a first number or a second number of separate phases; and multiple mixer modules (83, 85, 87, 89) having inputs connected to an output of 5 the low noise amplifier. The receiver has a configurable resistor network (76). The receiver is configured such that it can operate in a first mode (78) with said plurality of signals having said first number of phases or a second mode (80) with said plurality of signals having said second number of phases. The configurable resistor network enables the receiver to operate in the first mode in a first configuration, and 10 the second mode in a second configuration. The mixer modules are employed during the operation of the first mode and the second mode. [Figure 5]
(FR) L'invention concerne un récepteur radiofréquence configurable (74). Le récepteur comprend au moins un amplificateur à faible bruit (86a, 86b) ; un agencement d'oscillateur permettant de produire une pluralité de signaux ayant un premier nombre ou un second nombre de phases séparées ; et de multiples modules de mélangeur (83, 85, 87, 89) ayant des entrées connectées à une sortie de l'amplificateur à faible bruit. Le récepteur comprend un réseau de résistances configurable (76). Le récepteur est configuré de telle sorte qu'il peut fonctionner dans un premier mode (78) dans lequel ladite pluralité de signaux a ledit premier nombre de phases ou un second mode (80) dans lequel ladite pluralité de signaux a ledit second nombre de phases. Le réseau de résistances configurable permet au récepteur de fonctionner dans le premier mode dans une première configuration, et dans le second mode dans une seconde configuration. Les modules mélangeurs sont utilisés pendant le fonctionnement du premier mode et du second mode.
