Abstract

PURPOSE:To decrease the power capacity by using a capacitor charged in advance by a battery so as to supply power to a transmission circuit in a radio equipment making transmission in a burst way. CONSTITUTION:A transmission data inputted by a transmission message input device 1 is stored at first in a memory 2. Then the information stored in the memory 2 is transmitted to a transmission circuit 3 comprising a modulation circuit and a power amplifier section and a burst radio wave is transmitted from an antenna 4. The capacitor 6 charged by the battery 5 in advance is used to supply power to the transmission circuit 3. The timing of power supply to the transmission circuit 3 is taken just before a data is transmitted from the memory 2 to the transmission circuit 3. Thus, the electric energy stored in the capacitor 6 is utilized effectively.
