Abstract: Provided is a transmission circuit which is capable of compensating for an offset voltage and a sensitivity characteristic of a PA, and operating with low distortion and high efficiency. A regulator 18 supplies, to a PA 201, a voltage which is controlled in accordance with an amplitude signal to which a first offset value has been added. A regulator 19 supplies, to a PA 202, a voltage which is controlled in accordance with an amplitude signal to which a second offset value has been added. The PA 201 amplifies, in accordance with the voltage supplied from the regulator 18, a phase-modulated signal outputted from a phase modulator 13.

A digital block 11 controls the first and second offset values in accordance with temperature information T measured by a temperature measuring section 21.

Abstract: A phase modulation section (101) generates a first modulated signal including phase information. An amplitude signal control section (103) generates a second modulated signal including amplitude information. A waveform shaping section (104), when an amplitude of the second modulated signal is larger than a regulated value generates a waveform-shaped modulated signal. An amplitude modulated voltage supply section (105) amplifies the waveform-shaped modulated signal based on the supply voltage from a voltage control section (106) and supplies the amplified signal to a power amplification section (102). The power amplification section (102) amplifies the first modulated signal based on the amplitude modulated voltage, and outputs the resultant signal.

Abstract: A transmission circuit is provided which can output a stable transmission signal independently of the temperature characteristics of an amplitude modulating section. A signal generating section generates an amplitude signal and a phase signal. A regulator supplies a voltage which is controlled, depending on the amplitude signal, to the amplitude modulating section. An angle modulating section subjects the phase signal to angle modulation to output an angle-modulated signal. A temperature detecting section outputs temperature information of the amplitude modulating section. A gain control section controls a gain of a variable gain amplifier based on the temperature information of the amplitude modulating section. The variable gain amplifier amplifies the angle-modulated signal using the gain controlled by the gain control section.

Abstract: A wireless transmission apparatus of multi-mode operation with superior power efficiency is provided. Switches (115 and 117) are switched over in such a manner that a modulation signal outputted from a wireless GSM/EDGE (UB) signal formation circuit (101-3) of a high-frequency signal processing circuit (101) is outputted to a high-frequency power amplifier (104) at the time of output of a GSM modulation signal, and is outputted to a high-frequency amplifier (105) at the time of output of an EDGE modulation signal. As a result, the EDGE modulation signal is power amplified using a high-frequency power amplifier (105) for an UMTS modulation signal use that is compatible with regards to the EDGE modulation signal and the maximum output power and presence or absence of envelope fluctuation. It is therefore possible to amplify the EDGE modulation scheme wireless signal with high efficiency.

The voltage adjusting instrument determines a DC offset voltage on the basis of a level control signal indicating the level of the amplitude modulation signal and generates the amplitude modulation signal to which the DC offset voltage is added.

Further, the series resonant circuit 106 is connected at the other end to an output side of the second amplification element 102b. The series resonant circuit 106 resonates with a second-order harmonic frequency, thereby canceling out the second-order harmonic component.
