Abstract

The embodiment of the application provides a radio frequency circuit and electronic equipment. The radio frequency circuit comprises a radio frequency transceiving module, a first filtering element, asecond filtering element, a radio frequency switch and an antenna. In the radio frequency circuit provided by the embodiment of the application, when a first radio frequency signal and a second radiofrequency signal transmitted and sent by the radio frequency transceiving module comprise signal components with the same frequency, filtering is carried out respectively by the filtering elements indifferent signal paths, so that not only can carrier aggregation of the first radio frequency signal and the second radio frequency signal be implemented, but also mutual interference between the first radio frequency signal and the second radio frequency signal can be avoided, thereby improving diversity for the electronic equipment to carry out carrier aggregation on the radio frequency signals.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a radio frequency circuit and electronic equipment. Background technique [0002] With the development of communication technologies, mobile terminals can support more and more communication frequency bands. For example, an LTE (Long Term Evolution, long term evolution) communication signal may include a signal with a frequency between 700 MHz and 2700 MHz. [0003] The radio frequency signals that the mobile terminal can support can be classified into low frequency signals, intermediate frequency signals and high frequency signals. Wherein, each of the low-frequency signal, the intermediate-frequency signal and the high-frequency signal includes a plurality of sub-frequency band signals. Each sub-band signal needs to be transmitted to the outside world through an antenna. [0004] Thus, a carrier aggregation (Carrier Aggregation, CA for short) technology ...
