Embodiment

[0040] This example will specifically explain the architecture of the communication terminal 1000, the antenna device 100 and the radio frequency front end disclosed in the present invention.

[0041] Such as figure 1 As shown, the communication terminal 1000 provided in this example realizes its wireless communication through the built-in antenna device 100 . The antenna device 100 transmits radio frequency signals of relevant frequency bands to the outside and receives radio frequency signals of relevant frequency bands through its internal modules. Of course, the communication terminal 1000 not only includes the antenna device 100, but also includes other modules, such as a processor, a user interface, and a memory. Communication terminals are, for example, personal digital assistants (PDAs), mobile phones, plug-in cards in notebook computers, wireless tablet computers, and the like.

[0042] Such as figure 2 As shown, the antenna device 100 in this example also include...

Abstract

The invention provides a radio frequency front-end architecture, an antenna device and a communication terminal. In one aspect, the invention provides a radio frequency front-end architecture. The radio frequency front-end architecture comprises a main radio frequency front-end module and an auxiliary radio frequency front-end module; according to the communication terminal provided by the invention, the radio frequency front-end architecture on the internal antenna device is optimized, and the communication terminal can work in a multi-antenna working mode to receive and send multiple paths of radio frequency signals. According to the invention, the radio frequency front-end architecture is relatively simple in structure; only two radio frequency front-end modules are needed to realize multi-path emission and multi-path reception of radio frequency signals. Different frequency band signals needing to be accessed can be flexibly controlled and adjusted; moreover, the low-noise amplifiers in the radio frequency front-end architecture support the amplification of multi-band signals, thereby guaranteeing the implementation of 1T4R and 2T4R functions in fewer radio frequency front-endmodules, guaranteeing the implementation of abundant functions of the radio frequency front-end architecture, and reducing the area of the radio frequency front-end architecture.

Description

technical field [0001] The present invention relates to the field of communication terminal wireless communication systems, in particular to an antenna device on a communication terminal, and further relates to a radio frequency front-end architecture in the antenna device. Background technique [0002] With the rapid development of mobile communication technology, such as figure 1 As shown, on the communication terminal 1000 , it realizes its wireless communication through the built-in antenna device 100 . With the development and application of the fifth-generation mobile communication technology (5G), smart devices, especially 5G technology in mobile terminals, are facing new challenges. The realization of technical advantages such as faster network transmission speed, greater network capacity and lower network delay in 5G technology requires further optimization of 5G antenna technology. Existing antenna devices generally include a baseband module, a radio frequency tr...
