Title:
RADIO-FREQUENCY CIRCUIT, COMMUNICATION TERMINAL AND RADIO-FREQUENCY TRANSCEIVING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/015113
Kind Code:
A1
Abstract:
Disclosed are a radio-frequency circuit, a communication terminal and a radio-frequency transceiving method. The radio-frequency circuit comprises a first signal transceiving module, a second signal transceiving module, a first changeover switch, a controller, a first communication branch and a second communication branch, wherein the first signal transceiving module and the second signal transceiving module are respectively connected to two communication ports at one end of the first changeover switch, the first communication branch and the second communication branch are respectively connected to two communication ports at the other end of the first changeover switch, and a control port of the first changeover switch is connected to the controller; and an operating frequency band of the first communication branch does not overlap with an operating frequency band of the second communication branch. In the present disclosure, two signal transceiving modules can share two communication branches by means of the changeover of a changeover switch, thereby effectively reducing signal interference between the two signal transceiving modules; and both the signal transceiving modules realise full frequency band operation, thus making full use of a wireless frequency spectrum.
