Problems solved by technology

That is, either work in the bandwidth of 700MHz to 1GHz, or work in the bandwidth of 1GHz to 2.6GHz, these two channels cannot work at the same time
It cannot meet the requirements of LTE CA. LTE CA requires the carrier aggregation frequency bands to work at the same time. For example, B3+B8 CA, Band 3 is the 1700MHz frequency band, and Band 8 is the 900MHz frequency band. To meet the CA requirements, the 1700MHz frequency band and 900MHz frequency band must be simultaneously Work

Abstract

The present invention discloses a radio frequency circuit, an antenna apparatus and a mobile terminal. The radio frequency circuit comprises at least two carrier aggregation circuits, and a tuning switch circuit. The carrier aggregation circuit has a preset matching attribute. The preset matching attribute is corresponding to composite attributes consisting of at least one frequency band. The tuning switch circuit is electrically connected with the at least two carrier aggregation circuits. The tuning switch circuit is used for being electrically connected with an antenna and is used for selecting one of the at least two carrier aggregation circuits, so that the one selected carrier aggregation circuit of the at least two is communicated with the antenna. The radio frequency circuit can simultaneously support at least two frequency bands of a carrier aggregation combination.

Description

technical field [0001] The invention belongs to the field of radio frequency technology, and in particular relates to a radio frequency circuit, an antenna device and a mobile terminal. Background technique [0002] Traditional LTE (Long Term Evolution, Long Term Evolution) CA (Carrier Aggregation, Carrier Aggregation) generally requires several different LTE frequency bands to work at the same time. For example, the carrier aggregation of B3+B8 requires the two frequency bands of LTE Band 3 and LTE Band 8 to work at the same time. There are more and more CA combinations, including low-frequency + mid-frequency CA combinations, low-frequency + high-frequency CA combinations, mid-frequency + high-frequency CA combinations, and low-frequency + mid-frequency + high-frequency CA combinations. , which brings great challenges to antenna design. [0003] The traditional methods to increase antenna bandwidth are generally: [0004] An antenna tuner (equivalent to a switch, for exa...
