  • Publication number: 20210050876
    Abstract: A radio frequency module includes a power amplification element, a transmission filter, and a transmission matching element, which are transmission-only components for processing only a transmission signal, a low noise amplification element, a reception filter, and a reception matching element, which are reception-only components for processing only a reception signal, an antenna switch, which is a transmission-reception dual-use component for processing both a transmission signal and a reception signal, and a first module board and a second module board, which are arranged to face each other. The transmission-only components are mounted on a main surface of the first module board, and the reception-only components and the transmission-reception dual-use component are mounted on respective main surfaces of the second module board.

  • Publication number: 20200251459
    Abstract: A high-frequency module includes a mounting substrate having main surfaces 30a and 30b, a first circuit component mounted on the main surface 30a, a second circuit component mounted on the main surface 30b, an external connection terminal arranged on the main surface 30b side relative to the main surface 30a with respect to the mounting substrate, a long via conductor connected to the first circuit component, passing through the mounting substrate, and having a substantially long shape when the mounting substrate is viewed in a plan view, and a metal block arranged on the main surface 30b side relative to the main surface 30a with respect to the mounting substrate and connecting the long via conductor and the external connection terminal. When the mounting substrate is viewed in a plan view, the first circuit component overlaps the long via conductor and the metal block overlaps the long via conductor.

  • Publication number: 20200220635
    Abstract: A filter circuit includes a first switch circuit that exclusively connects a first common terminal to either of a first selection terminal and a second selection terminal; a first signal terminal that is connected to the first selection terminal and that is for communicating a first communication signal belonging to a first frequency range, which is a frequency range of a first communication band; a second signal terminal that is connected to the second selection terminal and that is for communicating a second communication signal belonging to a second frequency range, which is the frequency range of a second communication band and which is at least partially overlapped with the first frequency range; and a first band pass filter one end of which is connected to the first common terminal and which uses both the first frequency range and the second frequency range as pass bands.

  • Publication number: 20200212529
    Abstract: Isolation characteristics of a directional coupler are improved. A high-frequency module (1) includes a substrate (2) and a directional coupler (5) provided on the substrate (2). The directional coupler (5) includes a main line (51), a sub line (52), and an impedance adjustment portion (7). The sub line (52) is electromagnetically coupled to the main line (51). The impedance adjustment portion (7) is provided in the sub line (52), and adjusts impedance of the directional coupler (5). The impedance adjustment portion (7) is electrically connected to an inductor of the substrate (2).
