    Abstract: A transmitting method and a transmitter apparatus, which need no manual adjustment, are disclosed. A delay amount of a delay means is automatically adjusted such that an out-of-band distortion component of a transmission signal is minimized, and a correct timing is produced by the method and the apparatus. In this transmitter apparatus, a first delay means adjusts a control timing over a voltage that controls a power amplifying means, and a distributor distributes an output from the power amplifying means in order to feedback parts of the output. A distortion adjusting means calculates a distortion component of the transmission signal by using the signal fed back by the distributor, and adjusts automatically a delay amount of the first delay means so as to minimize the distortion component. This structure allows eliminating manual adjustment, and obtaining high power-efficiency with fewer distortions.

    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.
