RADIO COMMUNICATION DEVICE, RADIO COMMUNICATION METHOD, AND RADIO COMMUNICATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To implement power saving and reduction in the number of components.SOLUTION: A radio communication device 10 includes a switching control unit 41 that makes a DCDC converter 15 be a power supply for an amplifier 11 corresponding to a first band. The switching control unit 41 also switches an amplifier 12's connection relation with a battery 14 and the DCDC converter 15, on the basis of a magnitude relation between the DCDC converter 15's setting voltage corresponding to transmission power of the first band and a first threshold and a magnitude relation between the DCDC converter 15's setting voltage corresponding to transmission power of a second band and a second threshold.SELECTED DRAWING: Figure 1
