Abstract: First to fourth circuits are connected to corresponding first to fourth antenna terminals. The first to fourth circuits transmit and receive a signal of TDD and a signal of FDD. The first to fourth circuits transmit and receive a signal of MIMO. The third circuit receives a signal of a satellite positioning system. The lower limit of the frequency of the signal received by the third circuit and the fourth circuit is higher than the lower limit of the frequency of the signal received by the first circuit and the second circuit.

Abstract: A multiband transmission module includes a power amplifier and a multiband isolator. An output end of the power amplifier is connected to a single input terminal of the multiband isolator. The multiband isolator includes a low-frequency individual isolator and a high-frequency individual isolator. Input ends of the individual isolators are connected to the single input terminal of the multiband isolator. Output ends of the individual isolators are respectively connected to a low-frequency output terminal and a high-frequency output terminal of the multiband isolator.

Abstract: A matching network is a matching network of a power amplifier circuit that outputs a signal obtained by a differential amplifier amplifying power of a high-frequency signal. The matching network includes an input-side winding connected between differential outputs of the differential amplifier; an output-side winding that is coupled to the input-side winding via an electromagnetic field and whose one end is connected to a reference potential; a first LC series resonant circuit including a capacitive element and an inductive element connected in series with each other, and being connected in parallel with the input-side winding; and a second LC series resonant circuit including a capacitive element and an inductive element connected in series with each other, and being connected in parallel with the output-side winding.

Abstract: A high-frequency-signal transceiver circuit transmits and receives a signal between first to sixth antenna terminals and terminals near a high-frequency circuit. The high-frequency-signal transceiver circuit includes first to sixth circuits connected to the corresponding first to sixth antenna terminals. One of the first to sixth circuits transmits and receives only a signal of time division multiplexing communication.
