摘要： In a semiconductor device using an emitter top heterojunction bipolar transistor having a planar shape in a ring-like shape, a structure is provided in which a base electrode is present only on an inner side of a ring-like emitter-base junction region. This allows reduction of base/collector junction capacitance per unit emitter area, whereby a semiconductor device having high power adding efficiency and high power gain suitable for a power amplifier can be realized. Further, in a multistage power amplifier including first and second amplifier circuits each having one or more of bipolar transistors, a bipolar transistor in the first amplifier circuit uses an emitter having a planar shape in a rectangular shape, and a bipolar transistor in the second amplifier circuit uses an emitter having a ring-like shape and a base electrode only on the inner side of the emitter.

摘要： For use in an amplifier configuration including a high-power amplifier and a low-power amplifier which are always interconnected in terms of high frequencies and between which switching is made using no switches, a highly stable high-frequency power amplifier module with high isolation between the amplifiers is provided. To reduce wrapping around from a low-power amplifier section in an activated state to a high-power amplifier section in a deactivated state or from the high-power amplifier section in an activated state to the low-power amplifier section in a deactivated state, an input matching circuit having high isolation characteristics is included in an input matching circuit portion which does not have much to do with amplifier efficiency. Switching of each of the amplifier sections between an activated state and a deactivated state is effected by control using bias input terminals.
