Abstract: A self-calibrating modulator apparatus (300) includes a modulator having a controlled oscillator (326) and an oscillator gain calibration circuit (304). The oscillator gain calibration circuit includes an oscillator gain coefficient calculator (332) 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) (334), 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.

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. The waveform shaping section (104) adjusts the regulated value in accordance with a factor for changing a distorted power generated by the power amplification section (102), such that an ACP generated by the power amplification section (102) becomes a first predetermined value or smaller.

Abstract: 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).

Abstract: A transmission circuit operating at a high efficiency and a low distortion is provided. A signal generation section (11) generates a vector signal and an amplitude signal. A vector modulation section (13) performs vector modulation on the vector signal. An amplification section (15) amplifies the signal processed with the vector modulation. A signal processing section (12) performs predetermined signal processing on the amplitude signal and outputs the resultant signal. A regulator (14) controls a voltage to be supplied to the amplification section (15) based on the magnitude of the signal which is output from the signal processing section (12). The signal processing section (12) determines whether or not the amplitude signal exceeds a threshold value at an interval of a predetermined time period, selects a discrete value to be output based on the determination result, and outputs a signal having the selected discrete value.

Abstract: In first mode where the power level of a transmission output signal (S6) increases, output from a multiplier (2) is inputted to an amplitude modulation signal amplifier (4) and a high frequency power amplifier (5) performs amplitude modulation of a high frequency phase modulation signal (S4) with a power supply voltage from the amplitude modulation signal amplifier (4) by using the nonlinear region. In second mode where the power level of the transmission output signal (S6) decreases, output from the multiplier (2) is inputted to a variable gain amplifier (7) where amplitude modulation of the high frequency phase modulation signal (S4) is carried out. The amplitude modulated signal is outputted without passing through the high frequency power amplifier (5).

Abstract: PROBLEM TO BE SOLVED: To obtain stable characteristics by controlling a time difference between an amplitude signal and a phase signal to an optimal point without depending on a modulation signal and without increasing the scale of a circuit scale. SOLUTION: A multiplier 170 multiplies a digital amplitude signal obtained by performing analog-to-digital (A/D) conversion on an amplitude signal and a digital angle modulation signal corresponding to a signal obtained by performing A/D conversion on an angle modulation signal to spuriously generate a digital modulation signal corresponding to a signal obtained by A/D conversion on a modulation signal generated by an amplitude modulator 140. A distortion calculator 180 then calculates distortion of the digital modulation signal and on the basis of the distortion of the digital modulation signal, a controller 190 controls a delay time. A delay adjuster 130 adjusts a delay time until the amplitude signal is input to the amplitude modulator 140 or a delay time until the angle modulation signal is input to the amplitude modulator 140.
