Abstract
A semiconductor device includes a transmission power amplifier having cascaded MOSFET amplification stages disposed over a main surface of a semiconductor substrate. A CMOSFET control circuit controls the amplification stages. A first capacitor is also provided having upper and lower metal film electrodes formed over the main surface of the semiconductor substrate. The amplification stages are electrically coupled to one another via an inter-stage matching circuit which includes the first capacitor.
