摘要: A bipolar transistor includes a collector layer, a base layer, and an emitter layer that are formed in this order on a compound semiconductor substrate. The emitter layer is disposed inside an edge of the base layer in plan view. A base electrode is disposed on partial regions of the emitter layer and the base layer so as to extend from an inside of the emitter layer to an outside of the base layer in plan view. An insulating film is disposed between the base electrode and a portion of the base layer, with the portion not overlapping the emitter layer. An alloy layer extends from the base electrode through the emitter layer in a thickness direction and reaches the base layer. The alloy layer contains at least one element constituting the base electrode and elements constituting the emitter layer and the base layer.

摘要: A cavity elongated in one direction is formed in a protective film covering the conductive pattern of the topmost conductive layer of a multilayer wiring substrate. The cavity exposes part of the conductive pattern. A first via-conductor extends downward from the conductive pattern of the topmost conductive layer at least until that of a second conductive layer. Second via-conductors extend downward from the conductive pattern of the second or third conductive layer at least until that of a conductive layer one below. As viewed from above, the first via-conductor and the cavity partially overlap each other. At least two second via-conductors are disposed to sandwich the cavity therebetween. The difference between the smallest gap between the cavity and the second via-conductor at one side and that between the cavity and the second via-conductor at the other side is smaller than the smallest gap between the cavity and the second via-conductors.

摘要: A power amplifier module includes an amplifier transistor and a bias circuit. A first power supply voltage based on a first operation mode or a second power supply voltage based on a second operation mode is supplied to the amplifier transistor. The amplifier transistor receives a first signal and outputs a second signal obtained by amplifying the first signal. The bias circuit supplies a bias current to the amplifier transistor. The bias circuit includes first and second resistors and first and second transistors. The first transistor is connected in series with the first resistor and is turned ON by a first bias control voltage which is supplied when the first operation mode is used. The second transistor is connected in series with the second resistor and is turned ON by a second bias control voltage which is supplied when the second operation mode is used.
