Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of unwanted radiation upon powering-on even under a low temperature and to shorten a waiting time until shifting to a stable operation state.
SOLUTION: After apparatus activation, a final-stage amplifier 5 is operated for class-A operation until achieving a stable operation state, thereby promptly guiding an apparatus into stable operation enabled state and during the operation, a transmission signal is suspended by a transmission signal interruption section 4 so as not to incur unwanted radiation. Furthermore, when it is determined by a stable operation determining section 6 that the apparatus is shifted to the stable operation enabled state, operation of the final-stage amplifier 5 is switched to a normal operation mode (e.g., class-AB operation mode) and suspension by the transmission signal interruption section 4 is canceled.
