摘要： A signal generation section generates an amplitude signal and an angle-modulated signal. An adaptive compensation filter performs waveform shaping on the amplitude signal in accordance with a magnitude of the amplitude signal. An amplitude amplification section outputs a signal proportional to a magnitude of the signal subjected to waveform shaping in the adaptive compensation filter. An amplitude modulation section amplitude-modulates the angle-modulated signal by the signal outputted from the amplitude amplification section and outputs the resulting signal as a modulated signal. Characteristics of the adaptive compensation filter are inverse characteristics of transfer characteristics from an input of the amplitude amplification section to an output of the amplitude modulation section.

摘要： A transmission circuit for outputting transmission signals with a low distortion and a high efficiency over a wide range of output power is provided. A signal generation section (11) generates an amplitude signal and a phase signal. An angle modulation section (12) performs angle modulation on the phase signal and outputs an angle-modulated signal. A regulator (14) receives the amplitude signal via a variable gain amplification section (18) and supplies a voltage controlled based on the magnitude of the amplitude signal to the amplitude modulation section (15). The amplitude modulation section (15) performs amplitude modulation on the angle-modulated signal and outputs a modulated signal to the variable attenuation section (16). When the value of power information is smaller than a predetermined threshold value, the control section (19) increases the gain of the variable gain amplification section (18) and the attenuation of the variable attenuation section (16).

摘要： A self-calibrating modulator apparatus includes a modulator having a controlled oscillator and an oscillator gain calibration circuit. The oscillator gain calibration circuit includes an oscillator gain coefficient calculator configured to calculate a plurality of frequency dependent oscillator gain coefficients from results of measurements taken at the output of the controlled oscillator in response to a test pattern signal representing a plurality of different reference frequencies. The plurality of frequency dependent gain coefficients determined from the calibration process are stored in a look up table (LUT), where they are made available after the calibration process ends to scale a modulation signal applied to the modulator. By scaling the modulation signal prior to it being applied to the control input of the controlled oscillator, the nonlinear response of the controlled oscillator is countered and the modulation accuracy of the modulator is thereby improved.
