Abstract
Provided is a transmitter which is small in size and operates with high efficiency and compensates a delay error with high accuracy. A signal generation sectionoutputs a PM test signal and an AM test signal. The AM test signal is inputted to a multipliervia a delay adjustment sectionand a regulator. The PM test signal is inputted to the multipliervia the delay adjustment section. A power measurement sectionmeasures an average power of a multiplication signal which is outputted from the multiplierand outputs a measured value to a control section. The control sectiondetermines an amplitude delay time and a phase delay time on the basis of the inputted measured value and sets the determined delay times in the delay adjustment section
