Abstract: In an electronic component, a package includes a resin portion and a plurality of land electrodes. The resin portion has a first main surface and a second main surface facing each other in a predetermined direction and covers an IC chip. The plurality of land electrodes includes one first land electrode and three or more second land electrodes, which are the remaining land electrodes other than the first land electrode. The area of the first land electrode is larger than the area of each of the three or more second land electrodes in plan view from the predetermined direction. The plan-view shape of the first land electrode is different from the plan-view shapes of the three or more second land electrodes in plan view from the predetermined direction.

Abstract: Provided is a mount component that is for forming a directional coupler consisting of a main line and a sub line. Out of the main line and the sub line, only the sub line is formed on or in the mount component. The main line is formed on or in a mounting substrate on which the mount component is mounted and is not formed on or in the mount component. When the mount component is mounted on the mounting substrate, the main line and the sub line electromagnetically couple with each other and as a result a directional coupler is formed.

Abstract: A switch module includes a first terminal, first and second filters, and first and second switches. Impedance of the first filter for a signal in a stop band is capacitive. When the first switch is turned OFF, impedance of the first switch is capacitive, and impedance of the first filter seen from an end portion of the first switch connected to the first filter is not in a short state and impedance of the first filter seen from the first terminal is in an open state.

Abstract: An amplification circuit includes a filter circuit, an amplifier, a capacitor, a bypass line, and a switch circuit that includes a first FET and a second FET connected in series between one end and the other end of the bypass line, a first resistance element connected in series to a gate of the first FET, and a second resistance element connected in series to a gate of the second FET. A first control signal is supplied to the gate of the first FET. A second control signal is supplied to the gate of the second FET. A product of a gate length and a gate width of the first FET and a resistance value of the first resistance element is smaller than a product of a gate length and a gate width of the second FET and a resistance value of the second resistance element.
