Patent ID: 7289778

Claim:
A power circuit to supply power a transmission power amplifier of a communication device to amplify a transmission signal having a burst period and a non-burst period occurring alternately in a repeated manner, said power circuit comprising: a power supplying unit to supply a first power to said transmission power amplifier, and a power storing section to accumulate said first power during said non-burst period as an accumulated second power, and to feed the accumulated second power to said transmission power amplifier in addition to said first power being supplied from said power supplying unit as said power to said transmission power amplifier during said burst period, wherein said power storing section is configured to be charged, when a voltage of said power storing section becomes lower than a voltage of said power supplying unit during said burst period, until a voltage of said power storing section becomes almost equal to a voltage of said cower supplying unit during said non-burst period occurring subsequent to said burst period.
