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: PROBLEM TO BE SOLVED: To provide a transmission circuit operating with high linearity and with low noise.
SOLUTION: An AM variable fc filter 102 uses an AM cutoff frequency to remove a high frequency component from an amplitude signal. An amplifier 105 supplies a power amplifier 107 with a voltage which is a result of amplifying the amplitude signal output from the AM variable fc filter 102. A PM variable fc filter 103 uses a PM cutoff frequency to remove a high frequency component from a phase signal. A phase modulator 104 phase-modulates the phase signal output from the PM variable fc filter 103 to output a high-frequency phase-modulated signal. The power amplifier 107 amplifies the high-frequency phase-modulated signal by using the voltage supplied from the amplifier 105, and outputs a resultant signal as a transmission signal. The AM variable fc filter 102 and the PM variable fc filter 103 respectively control the AM cutoff frequency and the PM cutoff frequency such that the AM cutoff frequency and the PM cutoff frequency each have an opposite characteristic to that of an output power of the transmission signal.

Abstract: PROBLEM TO BE SOLVED: To provide a transmitting circuit capable of reducing reception band noise generated in an amplitude amplification section without causing loss in a main signal while reducing noise concurrently with suppression of modulation distortion. SOLUTION: A signal generating section 10 outputs an amplitude signal and a frequency signal by conducting signal processing on input data. A regulator 31 outputs a signal that is proportional to the magnitude of the amplitude signal. The signal output from the regulator 31 passes through a low pass filter 41, and is input into a power amplifier 51. The power amplifier 51 conducts an amplitude modulation on a frequency signal on which an angle modulation is conducted by an angle modulation section 20, by using a signal output from the low pass filter 41. A controlling section 60 controls an attenuation amount of a radio frequency component at the low pass filter 41 based on information such as a modulation method and modulation condition of the input data, the reception band, output power and frequency of the modulated signal and the like.
