Abstract

The present invention provides a radio frequency circuit and electronic equipment. The radio frequency circuit includes: a radio frequency transceiver with a first transmitting port, a first radio frequency module connected to a first antenna array, a second radio frequency module connected to a second antenna array, and a first radio frequency module connected to a second antenna array. A switch, the first input end of the first switch is connected to the first transmitting port, and the two output ends of the first switch are respectively connected to two radio frequency modules; when the first switch is in the first state, the first transmitting port and the second A radio frequency module is connected; when the first switch is in the second state, the first transmitting port is connected to the second radio frequency module. The invention can make the transmitting port select different paths, reduce the problem of large path loss caused by radio frequency wiring, and improve the antenna switching performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency circuit and electronic equipment. Background technique [0002] 5G (5th generation mobile networks, the fifth generation of mobile communication technology) supports two methods in the development process: 1T4R (1 transmission and 4 reception) and 2T4R (2 transmission and 4 reception). The 5G NR (New Radio, new air interface) frequency band supports 1T4R and 2T4R SRS (Sounding Reference Signal, reference signal for detection) antenna rotation transmission and antenna switching transmission technology. [0003] In the prior art, when performing 2T4R in a frequency band (such as N78), the amplifiers corresponding to the transmission signals of TX1 and TX2 are fixed. With TX1 as the fixed transmission of 1T4R, only the TX1 path can be used, that is, when there is only 2T4R, TX2 The corresponding PA (Power Amplifier, power amplifier) ​​will work. When the fou...
