La présente invention concerne un dispositif de réception, dans lequel la dégradation de la performance de réception est empêchée tout en empêchant une augmentation de la consommation d'énergie pour un nombre augmenté de canaux. Une pluralité de terminaux d'entrée reçoivent séparément un signal haute fréquence à partir d'une antenne. Une pluralité de circuits haute fréquence sont disposés en correspondance avec chacun de la pluralité des terminaux d'entrée et traite le signal haute fréquence à partir d'une antenne dans des bandes de fréquence différentes l'une de l'autre. Un circuit de génération de signal d'oscillation locale génère une fréquence d'oscillation locale qui correspond à la bande de fréquence de chacun de la pluralité des circuits haute fréquence. Une pluralité de circuits de mélange mélangent un signal haute fréquence de chaque circuit de la pluralité des circuits haute fréquence avec une fréquence d'oscillation locale correspondant à ce dernier et génèrent chacun un signal basse fréquence. Un circuit de fusion fait fusionner les signaux basse fréquence générés dans la pluralité de circuits de mélange et délivre le signal fusionné.
