Provided is a temperature-compensated circuit for a power amplifier through diode voltage control, in which a first resistor (Rref), a first diode (D 1 ), and a second diode (D 2 ) are connected to a reference voltage in series. The temperature-compensated circuit includes a second resistor (R 1 ) connected to the reference voltage, a third resistor (R 2 ) connected to the second resistor in series, a fourth resistor (Rc) having one terminal connected to the reference voltage, a fifth resistor (Re) having one terminal connected to ground, a bias transistor having a base terminal connected to a contact point (VS) between the second resistor and the third resistor, a collector terminal connected to the other terminal of the fourth resistor, and an emitter terminal connected to the other terminal of the fifth resistor, and a sixth resistor (Rf) connected between a series connection terminal between the first diode and the second diode, and the collector terminal of the bias transistor. The voltage of the collector terminal changes for compensation of a temperature.
