Abstract
A high frequency circuit includes a switch that includes terminals; a switch that includes terminals; a filter that has a pass band including a first band; and a diplexer that includes terminals. The diplexer includes a filter that is connected between the terminals and has a pass band including a first frequency band group containing the first band and a filter that is connected between the terminals and has a pass band including a second frequency band group. The terminal is connected to an antenna terminal. The terminals are connected to one terminal of the filter. The terminal is connected to the terminal. The terminal is connected to the terminal.
Claims12
A high frequency circuit comprising:
- a first antenna terminal;
- a first switch circuit that comprises a first terminal, a second terminal, and a third terminal;
- a second switch circuit that comprises a fourth terminal and a fifth terminal;
- a first filter that has a pass band comprising a first band;
- and
- a first multiplexer that comprises a first common terminal, a sixth terminal, and a seventh terminal,
- wherein the first multiplexer comprises:
- a second filter that is connected between the first common terminal and the sixth terminal, and that has a pass band comprising a first frequency band group but not a second frequency band group, the first frequency band group comprising the first band, and
- a third filter that is connected between the first common terminal and the seventh terminal, and that has a pass band comprising the second frequency band group but not the first frequency band group, and
- wherein the first terminal is connected to the first antenna terminal, the second terminal and the fourth terminal are connected to one terminal of the first filter, the third terminal is connected to the first common terminal, and the fifth terminal is connected to the sixth terminal.
