Multiline antenna switching switch

Abstract

The invention provides a multiline antenna switching switch. The multiline antenna switching switch is applied to an access terminal composed of a plurality of front-end antennas and a plurality of back-end links. The multiline antenna switching switch comprises: a plurality of the first radio frequency interfaces are used for connecting with a plurality of the front-end antennas respectively; a plurality of the second radio frequency interfaces are used for connecting with a plurality of the back-end links respectively; a communication interface is used for connecting the processor of the terminal and receiving switch-switching orders that the processor inputs; a switch-switching unit connected between the first radio frequency interfaces and the second radio frequency interfaces; and a control unit connected between the communication interface and the switch-switching unit and is used for controlling the switch-switching unit according to the switch-switching orders. The multiline antenna switching switch is capable of building free combination circuits composed of a plurality of radio frequency modules and a plurality of antennas flexibly, and improves user experience.

Description

technical field [0001] Embodiments of the present invention belong to the field of radio frequency technology, and in particular relate to a multi-line antenna switching switch. Background technique [0002] At present, smart phones are developing in the direction of multi-function, miniaturization and low radiation loss. The performance of the smart phone antenna for receiving electromagnetic waves directly determines the performance of mobile phone radiation and receiving electromagnetic wave signals, which affects the communication capabilities of mobile phones. In order to improve the communication capability of the mobile phone, more and more antennas on the mobile phone have emerged as the times require, and a technology that needs to switch the mobile phone antenna to a suitable position according to the use environment of the mobile phone has emerged. At present, the 2P2T switching technology is mostly used. This 2P2T switching technology mainly considers the switchi...

Problems solved by technology

At present, the 2P2T switching technology is mostly used. This 2P2T switching technology mainly considers the switching between the RF main antenna and the RF diversity antenna, and does not consider the use of WIFI / BT, GPS, etc. The module is also added to the ranks of antenna switching, and it is not possible to flexibly build a free combination line of multiple radio frequency modules and multiple antennas, which reduces the user experience
