Abstract:
A power amplification module includes: a first bipolar transistor in which a radio frequency signal is input to a base and an amplified signal is output from a collector; a second bipolar transistor that is thermally coupled with the first bipolar transistor and that imitates operation of the first bipolar transistor; a third bipolar transistor in which a first control voltage is supplied to a base and a first bias current is output from an emitter; a first resistor that generates a third control voltage corresponding to a collector current of the second bipolar transistor at a second terminal; and a fourth bipolar transistor in which a power supply voltage is supplied to a collector, the third control voltage is supplied to a base, and a second bias current is output from an emitter.
