Radio-frequency circuit

A radio-frequency circuit for multiband wireless communication in a plurality of frequency bands, the plurality of frequency bands including a first frequency band and a second frequency band, the first frequency band and the second frequency band both being higher than or equal to about 3 GHz and non-overlapping with each other, the first frequency band and the second frequency band having a spacing from each other less than or equal to about 10% of a lower one of a lower-bound frequency of the first frequency band and a lower-bound frequency of the second frequency band, the radio-frequency circuit comprising:

• a first antenna;
• a second antenna;
• a first multiplexer connected to the first antenna, the first multiplexer including:
• a first filter with a pass band that includes the first frequency band;
• and
• a third filter with a pass band different from the pass band of the first filter;
• and
• a second multiplexer connected to the second antenna, the second multiplexer including:
• a second filter with a pass band that includes the second frequency band;
• and
• a fourth filter with a pass band different from the pass band of the second filter.
