    Abstract: A receiver for processing a signal comprises a first amplifier circuit and a second amplifier circuit. The first amplifier circuit is operated in association with a first gain profile. The second amplifier circuit is operated in association with a second gain profile. The receiver further comprises a gain control circuit that determines a quality indicator associated with a modulated signal. The gain control circuit adjusts the first gain profile and the second gain profile based at least in part upon the determined quality indicator.

    Abstract: PROBLEM TO BE SOLVED: To lessen the influence of DC noise due to the AGC gain update in a direct conversion receiver.
    SOLUTION: As shown with AGC gain update timings t1-t4, etc. in the slot structure of received signals, the timing is shifted every time to disperse and lessen the influence of the DC noise peculiar to the direct conversion accompanying with the AGC gain update. If, especially, the slots of received signals have information (Data) with a high code correcting power and information (TPC, TFCI, PILOT) with a low code correcting power, the AGC gain update timing is shifted in the former information part to generate it, thereby more lessening the influence of the noise. The shift width of the AGC gain update timing is set to be greater than one symbol width of the received signal, thereby further lessening the influence of the noise due to the AGC gain update.

    Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient transmitter capable of covering an output level in a wide range.
    SOLUTION: The operation mode of a high frequency power amplifier 15 is designated to one between a linear operation mode and a saturation operation mode on the basis of an operation mode designation signal 107. The gain of a variable gain amplifier 14 provided at the preceding stage of the high frequency power amplifier 15 and the values of output voltage 109 and bias current supplied to the high frequency power amplifier 15 from a power voltage/bias current control circuit 17 are changed. In the case of the saturation operation mode, the gain of the variable gain amplifier 14 is configured so as to be always larger by a prescribed amount than in the case of the linear operation mode. This makes the high frequency power amplifier 15 operate in a designated operation mode to secure an output transmission power range widely.
