Abstract

Embodiments of the present invention disclose a circuit, a method and a mobile terminal for improving radio frequency isolation. The circuit includes: a switch module and at least two isolation control modules; the isolation control module receives signals of multiple frequency bands for outputting attenuated signal; the switch module is connected to the isolation control module for gating a radio frequency channel according to the received frequency band, the radio frequency channel corresponds to the isolation control module corresponding to the received frequency band, and outputs the isolation control module that meets the preset isolation degree. required signal. This solution improves the radio frequency isolation, and the space that can be saved depends on the frequency band combination required. The more combinations, the more space is relatively saved.

Description

technical field [0001] The invention relates to a radio frequency circuit, in particular to a circuit, a method and a mobile terminal for improving radio frequency isolation. Background technique [0002] With the continuous development and popularization of the fifth-generation mobile communication system 5G technology, people have higher and higher requirements for the user experience of the terminal. But at the same time, it is necessary to consider the compatibility of 2G\3G\4G existing networks, which undoubtedly poses a higher challenge to the design of our terminal equipment. The current terminal design needs to consider the EN-DC scenario where 5G and 4G are used at the same time, and the scenario of carrier aggregation CA between different frequency bands of 4G needs to be considered. In these simultaneous working scenarios, the problem of interference and mutual interference between the two must be considered. For example, if we do not have enough isolation in th...
