TRANSMITTER, TEMPERATURE COMPENSATION METHOD OF RF SIGNAL, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a transmitter with a temperature compensation function that is downsized more and smaller in the power consumption than prior arts. SOLUTION: A temperature compensation processing section 40 directly applies digital signal processing to a digital modulation signal being an output of a modulation signal generating circuit 30 in response to a temperature detected by a temperature detector 10 to carry out temperature compensation. Since the processed digital modulation signal passes through a D/A conversion circuit 50 after the temperature compensation processing, the required number of D/A conversion circuits 50 can be decreased by one in comparison with prior arts and downsizing and furthermore energy saving can be attained attended with above.
