Abstract
(EN)
Disclosed is a transmitting circuit wherein operation mode can be smoothly switched at the time of switching the operation mode of the transmitting circuit. A power amplifying unit (14) is provided with: a first input terminal supplied with a direct current voltage or a voltage corresponding to amplitude signals (M); a second input terminal to which signals outputted from the first variable gain amplifier (171) or signals outputted from a second variable gain amplifier (172) are inputted; and a third input terminal to which signals outputted from a first bias circuit (15) or signals outputted from a second bias circuit (16) are inputted. A control unit (11) switches the operation mode of the transmitting circuit such that at least the first input terminal, the second input terminal or the third input terminal of the power amplifying unit is not in the state wherein the signals are not inputted.

L'invention concerne un circuit émetteur dont la commutation du mode de fonctionnement s'effectue avec souplesse. Un module amplificateur de puissance (14) comprend : une première borne d'entrée recevant une tension continue ou une tension correspondant à des signaux d'amplitude (M) ; une deuxième borne d'entrée recevant des signaux issus d'un premier amplificateur à gain variable (171) ou des signaux issus d'un deuxième amplificateur à gain variable (172) ; et une troisième borne d'entrée recevant des signaux issus d'un premier circuit de polarisation (15) ou des signaux issus d'un deuxième circuit de polarisation (16). Un module de commande (11) commute le mode de fonctionnement du circuit émetteur de manière à ce que des signaux soient toujours reçus par au moins une des bornes parmi la première borne d'entrée, la deuxième borne d'entrée et la troisième borne d'entrée.
