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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Transmission circuit and communication apparatus using polar modulation method","description":"A transmission circuit adjust a difference between signal delay amounts in an amplitude path and a phase path with a low power consumption.
