Abstract: Bidirectional detection is performed with a suppressed increase in return loss at an output terminal. A bidirectional coupler includes a detection port, a main line connected to a first port and a second port, a sub-line, a termination circuit, a switch circuit that switches each of one end and another end of the sub-line to the termination circuit or the detection port, and a matching network disposed between the switch circuit and the detection port and including at least one of a first variable capacitor, a first variable inductor, or a first variable resistor. In a first mode for detecting a first signal, the switch circuit connects the one end of the sub-line to the detection port, and connects the other end of the sub-line to the termination circuit.

Abstract: A high-frequency module includes a semiconductor chip device that is mounted on an external circuit substrate by wire bonding. A switch forming section, a power amplifier forming section and a low noise amplifier forming section, realized by a group of FETs, which are active elements, are formed in the semiconductor chip device. Flat plate electrodes, which form capacitors are formed in the semiconductor chip device. Conductor wires that connect the external circuit substrate and the semiconductor chip device function as inductors. A group of passive elements that includes inductors and capacitors is formed. As a result, a high-frequency module that can be reduced in size while still obtaining the required transmission characteristic is realized.

Abstract: A directional coupler includes a main line, a sub-line electromagnetically coupled with the main line, a coupled output terminal, plural filters, filter switching circuits, and plural filter protecting switches. Each of the filter switching circuits is able to connect a corresponding one of the plural filters to one end of the sub-line and to the coupled output terminal. Each of the filter protecting switches is directly connected to a corresponding end of a corresponding one of the plural filters and is able to switch between a connection state and a disconnection state. The connection state is a state in which the corresponding end of the corresponding one of the plural filters is connected to a reference potential. The disconnection state is a state in which the corresponding end of the corresponding one of the plural filters is disconnected from the reference potential.
