Abstract

See full text

First and second frequency bands used for multiband communication are both higher than or equal to about 3 GHz, and do not overlap each other. The spacing between the first and second frequency bands is less than or equal to about 10% of the lower one of the lower-bound frequency of the first frequency band and the lower-bound frequency of the second frequency band. A radio-frequency circuit includes a first antenna, a second antenna, a first multiplexer connected to the first antenna, and a second multiplexer connected to the second antenna. The first multiplexer includes a first filter with a pass band including the first frequency band, and a third filter with a pass band different from the first filter. The second multiplexer includes a second filter with a pass band including the second frequency band, and a fourth filter with a pass band that differs from the second filter.
