Embodiment Construction

[0023] Regarding the features and technical content of the present invention, please refer to the following detailed description and accompanying drawings, which are provided for reference and illustration only, and are not intended to limit the present invention.

[0024] The invention provides a mobile terminal and its radio frequency architecture. Specifically, the mobile terminal of the present invention designs its radio frequency architecture according to the multi-antenna scheme, divides all frequency bands into N parts according to the characteristics of the frequency bands, and designs N antennas correspondingly for the mobile terminal, and allocates N antenna switches accordingly, respectively through The corresponding antenna switches feed frequency bands with different frequency band characteristics to different antennas, where N is an integer greater than or equal to 2.

Abstract

The invention provides a mobile terminal radio frequency framework comprising a plurality of frequency band modules, a plurality of antennae and a plurality of antenna switches, wherein each frequency band module respectively has different frequency band properties; the antennae are respectively matched with each frequency band module; and the antenna switches are used for connecting the sending and receiving signals of the frequency band modules with the antennae. The invention further provides a mobile terminal adopting the mobile terminal radio frequency framework. Through the technical scheme, the invention can optimize a framework matched with a plurality of antennae, reduce the cost and improve the radio frequency performance.

Description

【Technical field】 [0001] The present invention relates to the field of mobile terminals, in particular to a multi-antenna mobile terminal and its radio frequency architecture. 【Background technique】 [0002] Today's mobile communication has entered the 3G era, and various 3G terminals are continuously launched. But 2G network users still occupy a large share. Especially in countries and regions adopting GSM, WCDMA and other evolution routes, 2G network users still occupy a large share, so most of the existing mobile terminals adopt the dual mode of 2G and 3G. 2G and 3G dual-mode mobile terminals are characterized by supporting a large number of frequency bands, such as GSM four frequency bands (GSM850, GSM900, DCS, PCS) and WCDMA dual-frequency (WCDMA BC1 / BC8 or BC2 / BC5). Antenna design is a big test. [0003] As the current design of mobile terminals tends to be thinner and thinner, corresponding to more and more frequency bands supported, the antenna area of ​​the termi...
