Patent ID: 7068521

Claim:
An RF power amplifier module comprising: a semiconductor chip having a quadrilateral surface; and a mounting substrate having a main surface on which said semiconductor chip is mounted, said semiconductor chip having: a first electrode formed on a first area of a main surface of said semiconductor chip; a first amplifier, formed also on said first area of said main surface of said semiconductor chip, having an input port electrically coupled with said first electrode; a second electrode formed on a second area of said main surface of said semiconductor chip, the second area being another area which is different from the first area on said main surface of said semiconductor chip; and a second amplifier, formed also on said second area of said main surface of said semiconductor chip, having an output port electrically coupled with said second electrode, said mounting substrate having: a third electrode formed on said main surface of said mounting substrate and electrically coupled with said first electrode through a first wire; and a fourth electrode formed on said main surface of said mounting substrate and electrically coupled with said second electrode through a second wire, wherein an output port of said first amplifier is electrically coupled with an input port of said second amplifier within said RF power amplifier module, wherein said third electrode is disposed facing a first side selected from four sides of said semiconductor chip, and wherein said fourth electrode is disposed facing a second side selected from said four sides, said first side and said second side intersect each other at a corner selected from four corners of said semiconductor chip.
