Abstract: A transmission circuit adjust a difference between signal delay amounts in an amplitude path and a phase path with a low power consumption. An amplitude modulation section amplitude-modulates a phase modulation signal outputted from a phase modulation section with a voltage control signal provided by a regulator to generate a transmission signal for an output of an antenna. Similarly, a feedback signal generation section amplitude-modulates the phase modulation signal with a voltage control signal to generate a feedback signal. The signal is fed back to a delay adjustments sections used for calculating and adjusting the difference between the signal delay amounts in the amplitude path and the phase path. The feedback signal generation section is attained by a power amplifier having the same configuration as the amplitude modulation section and a smaller circuit scale.

Abstract: A signal generating section 10 outputs an amplitude signal and a frequency signal by conducting a signal processing on inputted data. A regulator 31 outputs a signal that is proportional to a magnitude of the amplitude signal. The signal outputted from the regulator 31 passes through a low pass filter 41, and is inputted 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, using a signal outputted from the low pass filter 41. A controlling section 60 controls an amount of attenuation of a radio frequency component at the low pass filter 41 based on information such as: a modulation method of the inputted data; a modulation condition of the inputted data; a reception band; an output power of a modulation signal; and a frequency of the modulation signal.
