摘要： A reduction is achieved in the primary-side input impedance of a transformer (voltage transformer) as an output matching circuit without involving a reduction in Q-factor. An RF power amplifier includes transistors, and a transformer as the output matching circuit. The transformer has a primary coil and a secondary coil which are magnetically coupled to each other. To the input terminals of the transistors, respective input signals are supplied. The primary coil is coupled to each of the output terminals of the transistors. From the secondary coil, an output signal is generated. The primary coil includes a first coil and a second coil which are coupled in parallel between the respective output terminals of the transistors, and each magnetically coupled to the secondary coil. By the parallel coupling of the first and second coils of the primary coil, the input impedance of the primary coil is reduced.

摘要： There is a need to provide a high-frequency power amplifier capable of reducing a talk current and reducing a phase deviation in output. The high-frequency power amplifier includes differently sized first through fifth power amplification transistors and impedance matching circuits for example. The high-frequency power amplifier changes a signal path to be used in accordance with a power specification signal. The high-frequency power amplifier uses a signal path from the first transistor to the second transistor in high power mode. The high-frequency power amplifier uses a signal path from the first transistor to the third transistor in medium power mode. The high-frequency power amplifier uses a signal path from the fourth transistor to the fifth transistor in low power mode. The high-frequency power amplifier is configured so that each of the signal paths includes the same number of stages of power amplification transistors and impedance matching circuits.

摘要： An area information generating unit generates plural pieces of area information each showing a partial area of a texture image. A polygon information generating unit generates polygon information including plural pieces of vertex information and an area ID. A rendering unit carries out interpolation on the texture coordinates of the vertices of a polygon on an output image to assign texture coordinates to each pixel located inside the polygon, and further acquires area information by referring to the area ID added to the polygon information and converts the texture coordinates assigned to each pixel of the output image in such a way that the texture coordinates fall within the area.
