Embodiments of the present invention provide a radio frequency circuit, an antenna device, and an electronic device. The radio frequency circuit includes a radio frequency transceiver, a radio frequency circuit switch chip and an antenna, wherein the radio frequency transceiver, the radio frequency circuit switch chip and the antenna are connected in sequence; the radio frequency circuit switch chip includes a first phase shifter component, a second A phaser component, a first switch component, and a combiner; the radio frequency transceiver includes a high-frequency transmitting port, an intermediate-frequency transmitting port and a low-frequency transmitting port, the high-frequency transmitting port is connected with the first phase shifter component, so The intermediate frequency transmitting port is connected to the second phase shifter component, and the low frequency transmitting port is used for outputting a low frequency signal to the combiner; the first switch component is used for connecting the first phase shifter component to the combiner. / or the second phase shifter assembly is connected to the combiner.
Description
technical field [0001] The invention relates to the communication field, in particular to a radio frequency circuit, an antenna device 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 is produc...
