摘要： A high frequency power amplifier maintains an excellent linearity regardless of a fluctuation of a load impedance and is downsized. The high frequency power amplifier detects an AC voltage amplitude at an output terminal of a final amplification stage transistor, and suppresses an input signal amplitude of a power amplifier when the voltage amplitude exceeds a predetermined threshold value.

摘要： For use in an amplifier configuration including a high-power amplifier and a low-power amplifier which are always interconnected in terms of high frequencies and between which switching is made using no switches, a highly stable high-frequency power amplifier module with high isolation between the amplifiers is provided. To reduce wrapping around from a low-power amplifier section in an activated state to a high-power amplifier section in a deactivated state or from the high-power amplifier section in an activated state to the low-power amplifier section in a deactivated state, an input matching circuit having high isolation characteristics is included in an input matching circuit portion which does not have much to do with amplifier efficiency. Switching of each of the amplifier sections between an activated state and a deactivated state is effected by control using bias input terminals.

摘要： The technical subject of the invention is to inhibit disconnection of electrodes caused by a step and bursting caused by residual air. That is, an object of the present invention is to provide a semiconductor device capable of overcoming a drawback due to the shape of a concave portion present in the zinc blende type compound semiconductor substrate in which the area of the bottom is larger than the surface in the cross sectional shape, as well as a manufacturing method thereof. According to the invention, a hole or step present in the semiconductor substrate constituting the semiconductor device is formed into a normal mesa shape irrespective of the orientation of the crystals on the surface of the semiconductor substrate. Accordingly, the present invention uses a novel wet etching solution having an etching rate for a portion below the etching mask higher than that in the direction of the depth of the semiconductor substrate.
