Abstract
A high-frequency module includes a high-frequency switch, filters (21 to 23), (31 to 33), and connection circuits (41 to 46). The high-frequency switch has filter-side terminals (Ps1 to Ps 6). The filters (21, 22, 23) each include a plurality of filters having characteristics different from each other. The filters (31, 32, 33) each include one type of filter. The connection circuits (41, 42, 43) connect the terminals (Ps1, Ps2, Ps3) of the high-frequency switch to the common terminals (Pc21, Pc22, Pc23) of the filters (21, 22, 23), respectively. The connection circuits (44, 45, 46) connect the terminals (Ps4, Ps5, Ps6) of the high-frequency switch to the filters (31, 32, 33), respectively. The connection circuits (41, 42, 43) are shorter than the connection circuits (44, 45, 46).
Claims20
A high-frequency module, comprising:
- a switch having a common terminal, and a first selection terminal and a second selection terminal one of which is selectively connected to the common terminal;
- a multiplexer connected to the first selection terminal;
- and
- a single filter connected to the second selection terminal, wherein
- an electrical distance of a first transmission path connecting the first selection terminal and the multiplexer is shorter than an electrical distance of a second transmission path connecting the second selection terminal and the single filter.
A high-frequency module, comprising:
- a high-frequency switch having an antenna-side terminal and a plurality of filter-side terminals, and selectively connecting one of the plurality of filter-side terminals to the antenna-side terminal;
- at least one first filter including a plurality of filters having characteristics different from each other, and a common terminal common to the plurality of filters;
- at least one second filter including one filter;
- at least one first circuit connecting a first terminal of the plurality of filter-side terminals and the first filter;
- and
- at least one second circuit connecting a second terminal of the plurality of filter-side terminals to one terminal of the second filter, wherein
- a signal transmission distance of the first circuit is shorter than a signal transmission distance of the second circuit.
