Document Type and Number:
Japanese Patent JP5585244
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize configuration which can adjust radio wave output radiated from an antenna while suppressing an increase of the number of components, increase in the size of device configuration, and increase in power consumption.SOLUTION: A portable radio communication terminal 1 comprises output control means, which includes voltage adjusting means capable of changing offset voltage of a baseband signal output by a signal output means and amplitude adjusting means capable of changing amplitude of the baseband signal output by the signal output means. And the output control means changes the level of a radio wave output from an antenna 40 by adjusting offset voltage of the baseband signal by the voltage adjusting means, and by adjusting amplitude of the baseband signal by the amplitude adjusting means.
