Abstract
Disclosed herein is a power amplifier for time division multiple access. The power amplifier for time division multiple access includes: power amplifiers power-amplifying input transmission signals and outputting the amplified signals; a power control unit using a time division multiple access type to control amplification of the power amplifiers; a switching unit formed at output terminals of the power amplifiers and the power control unit and outputting the amplified signals to an antenna based on a switching pass determined by the power control unit; and a timing control unit formed at an input terminal of the power control unit and determining turn-on time of a second signal by a level of an output signal generated by comparing a first signal with reference voltage.
