In a radio apparatus including a plurality of variable-gain amplifiers and at least one frequency converter which are connected in series, a gain controller includes a plurality of gain control lines and a gain control signal generator. The gain control lines are connected to the variable-gain amplifiers, respectively. The gain control signal generator individually generates a plurality of gain control signals which are supplied to the variable-gain amplifiers through the gain control lines, respectively.
Dans un appareil radio comportant une pluralité d'amplificateurs à gain variable et au moins un convertisseur de fréquence connectés en série, un contrôleur de gain est doté d'une pluralité de lignes de commande de gain et d'un générateur de signaux de commande de gain. Les lignes de commande de gain sont respectivement connectées aux amplificateurs à gain variable. Le générateur de signaux de commande de gain produit une pluralité de signaux de commande de gain qui sont transmis individuellement aux amplificateurs à gain variable via les lignes de commande de gain correspondantes.
