PROBLEM TO BE SOLVED: To provide a multi-band enabled communication terminal capable of satisfying demand for miniaturization, power saving and low pricing, and to provide a communication circuit and a communication method. SOLUTION: A distribution signal generator 12 generates a first distribution signal and a second distribution signal from a transmission signal outputted from a third frequency band output 11c. Then, a first amplifier 13a amplifies the first distribution signal, and a second amplifier 13b amplifies the second distribution signal. Thereafter, a synthesis processor 15 synthesizes the first distribution signal amplified by the first amplifier 13a and the second distribution signal amplified by the second amplifier 13b to send out the synthesized signal as radio waves of a third frequency band. Therefore, In the multi-band supported communication terminal 100 where radio communications are performed by signals of a first frequency band, a second frequency band, and the third frequency band, an amplifier having characteristics conforming to a transmission signal of the third frequency band can be omitted.
