    摘要： The envelope tracking power supply includes a plurality of variable voltage supplies. A power supply controller of a power amplifier controls the plurality of variable voltage supplies so as to precisely divide the power supply voltage in a high frequency area, based on the voltage distribution of a received transmitted base band signal, in order to maximize the power added efficiency of the power amplifier. The power supply controller includes a threshold memory including a plurality of first zones, and a frequency memory including a plurality of second zones. The power supply controller changes the threshold held in the first zones so that each second zone approaches the average of the second zones.

    摘要： When an output electrode of a power transistor in the final amplifying stage is coupled to a transmission line transformer TLT serving as an impedance matching circuit, a condition for impedance matching of the transmission line transformer is maintained. An RF amplifying device comprises a transmission line transformer coupled to an output electrode of a power transistor for generating transmission power to be fed to an antenna. The transmission power from the output electrode of the power transistor is fed to one end of a main line of the transmission line transformer, and one end of a secondary line of the transmission line transformer is coupled to an AC grounding node. The other end of the secondary line is coupled to the one end of the main line, thereby generating the transmission power to be fed to the antenna from the other end of the main line. At an energy coupling part where the main line of the transmission line transformer is in close proximity of, and opposite to the secondary line, coupling energy is transmitted from the secondary line to the main line. Coupling members electrically coupled to the output electrode of the power transistor are electrically coupled to a joint formed in either the main line, or the secondary line, at part of the energy coupling part.
