Patent ID: 7525813

Claim:
An RF power amplifier module including a power amplifier circuit, said RF power amplifier module comprising: a semiconductor chip having a main surface, said main surface being quadrilateral and having a pair of first sides and a pair of second sides perpendicular to the first sides; a mounting substrate having a mounting surface over which said semiconductor chip is mounted; an input stage transistor having a first input node and a first output node, disposed on the main surface of the semiconductor chip; an intermediate stage transistor having a second input node and a second output node, disposed on the main surface of the semiconductor chip, said first output node being electrically coupled to the second input node; an output stage transistor having a third input node and a third output node, disposed on the main surface of the semiconductor chip, said second output node being electrically coupled to the third input node, said input stage, intermediate stage and output stage transistors comprising the power amplifier circuit; an input terminal disposed on the mounting surface of the mounting substrate; an output terminal disposed on the mounting surface of the mounting substrate; an input bonding wire electrically coupling the input terminal and the first input node, said input bonding wire being disposed so as to cross over one of the first sides of the main surface of the semiconductor chip; and an output bonding wire electrically coupling the output terminal and the third output node, said output bonding wire being disposed so as to cross over one of the second sides of the main surface of the semiconductor chip.
