Abstract
In a high-frequency module, a first individual terminal in a switch IC is connected to a first filter and a third filter whose pass bands are far from each other. A low-pass-filter phase circuit including an inductor and a capacitor is connected between the first individual terminal and the first filter. A second individual terminal is connected to a second filter and a fourth filter whose pass bands are far from each other. A low-pass-filter phase circuit is connected between the second individual terminal and the second filter.
Claims8
A high-frequency module comprising:
- a switch IC including a common terminal and a plurality of individual terminals;
- and
- a plurality of filters connected to the individual terminals in the switch IC, for which a pass band is set for each communication signal;
- wherein
- the plurality of filters at least include a first filter having a frequency of a first communication signal as the pass band, a second filter having a frequency of a second communication signal as the pass band, the frequency band of the first communication signal being close to the frequency band of the second communication signal, and a third filter having a frequency of a third communication signal as the pass band, the frequency of the third communication signal being far from the frequencies of the first communication signal and the second communication signal;
- the first filter and the third filter are connected to a first individual terminal in the switch IC;
- and
- the second filter is connected to a second individual terminal in the switch IC.
