Abstract:
     The invention relates to a control circuit of output power of power amplifier, which comprises: a directed coupler electrically connected to the power amplifier to receive signal; a power controller electrically connected to the directed coupler to obtain one output power detecting signal, and electrically connected to one external circuit to obtain the first power set signal, wherein said power controller based on the output power detecting signal and the first power set signal, outputs the second power set signal and one time constant control circuit connected to the power controller to receive the second power set signal, to output one power control signal to the power amplifier to adjust the output power.
