The embodiment of the present invention discloses a radio frequency circuit, an antenna device and electronic equipment. The radio frequency circuit includes a first switch, a second switch, a third switch, a first phase shifter module, a second phase shifter module and a combination A circuit breaker, wherein the first phase shifter module is connected to the first switch input end, and the second phase shifter module is connected to the second switch input end, when the first switch and the second switch connect the first phase shifter module When both the group and the second phase shifter module are connected to the combiner, the high-frequency signal and the intermediate-frequency signal are carrier-aggregated to obtain the first aggregated signal, and the combiner aggregates the first aggregated signal and the low-frequency signal. The present invention can control radio frequency signals of different frequency bands to carry out carrier aggregation through a radio frequency circuit, thereby improving the diversity of carrying out carrier aggregation on radio frequency signals by electronic equipment.
Description
technical field [0001] The invention relates to the field of mobile communication, in particular to a radio frequency circuit, an antenna device and electronic equipment. Background technique [0002] With the development of terminal technology, the mobile terminal has gradually changed from simply providing communication equipment to a platform for general software operation. The platform no longer aims to provide call management, but to provide an operating environment including call management, game entertainment, office notes, mobile payment and other application software. With a large number of popularization, it has penetrated into people's All aspects of life and work. [0003] Currently, 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. The radio frequency signals that the mobile terminal ca...
