Abstract

The embodiment of the invention discloses a radio frequency circuit, a communication device and electronic equipment. The radio frequency circuit comprises M user identity recognition units, a radio frequency processing module and a radio frequency front end, wherein the radio frequency front end comprises N transmit-receive paths, M is an integer greater than 1, and N is an integer greater than or equal to M; the radio frequency processing module is connected with the radio frequency front end; the radio frequency processing module is used for determining M transceiving paths for the M user identity recognition units from the N transceiving paths, and controlling the M transmit-receive paths to transmit the radio frequency signals of the corresponding user identity identification units. Here, by using the radio frequency front end with a plurality of transceiving paths, a plurality of subscriber identity module units can share one radio frequency front end to realize a multi-communication function, such as a dual-card dual-pass function, and the dual-card dual-pass function can be realized by only needing one set of radio frequency processing module and radio frequency front end on hardware, so that the hardware cost is saved, and the hardware space occupation is reduced.

Description

technical field [0001] The present application relates to communication technology, in particular to a radio frequency circuit, communication device and electronic equipment. Background technique [0002] In the prior art, for an electronic device with dual cards, if the two cards are to communicate at the same time, it is necessary to set up independent radio frequency systems for the two cards in the electronic device to realize the dual-card dual-pass function. This kind of dual-card dual-pass design mainly relies on two different radio frequency systems, which causes the problem of high cost and large area occupation of electronic equipment, which is not suitable for the development needs of future electronic equipment. Contents of the invention [0003] In order to solve the above technical problems, the embodiments of the present application expect to provide a radio frequency circuit, a communication device, and an electronic device. [0004] The technical scheme o...
