Patent ID: 8204471

Claim:
A semiconductor device for use in a radio communication device of multi bands, comprising: a substrate including an upper surface, a plurality of wirings formed in the substrate, and a lower surface opposite to the upper surface; a semiconductor chip, including a main surface, a first low noise amplifier for a high frequency band formed on the main surface, a second low noise amplifier for a low frequency band different from the band of the first low noise amplifier formed on the main surface, a first mixer receiving signals from the first low noise amplifier, a second mixer receiving signals from the second low noise amplifier, a plurality of pads formed over the main surface, and a back surface opposite to the main surface, mounted over the upper surface of the substrate via a plurality of bump electrodes such that the main surface is faced to the upper surface of the substrate; and a plurality of external terminals formed on the lower surface of the substrate; wherein the pads include a first pad coupled to the first low noise amplifier, a second pad, and a plurality of third pads, wherein the first pad is arranged between the third pads adjacent to each other in a plan view, and wherein the second pad is arranged between a part of the third pads.
