Radio frequency circuit, antenna component, and electronic device

Abstract

The embodiment of the invention provides a radio frequency circuit, an antenna component, and an electronic device. The antenna component comprises a first first antenna structure, a second antenna structure, a radio frequency module, a transmitting circuit and a receiving circuit; the radio frequency module comprises a transmitting end and a receiving end; the transmitting circuit is connected between the transmitting end and the first antenna structure, the transmitting circuit is used for transmitting a first radio frequency signal of the radio frequency module to the first antenna structure; and the receiving circuit is connected between the receiving end and the second antenna structure, the receiving circuit is used for transmitting a second radio frequency signal received by the second antenna structure to the radio frequency module, the receiving circuit and the transmitting circuit are arranged to be separated from each other, and the first radio frequency signal and the second radio frequency signal are located at the same frequency band. The transmission and reception of antenna signals at the same frequency band are separately tuned, and both of the transmission and reception can be tuned to the optimal efficiency point.

AI Technical Summary

Problems solved by technology

[0003] In the existing technical solution, since the transmitting antenna signal and the receiving antenna signal are placed in the same channel for tuning, and multiple frequency bands share one tuning channel, at the same time, because the frequency of the antenna signal transmitted by the frequency division duplex antenna in the same frequency band is different from that of the received antenna signal, Some antenna signals received and transmitted in the same frequency band have a frequency difference of hundreds of megabytes, so it is often impossible to tune to the best efficiency point for both transmission and reception. It is often necessary to ensure transmission performance at the expense of reception performance, or to ensure reception performance at the expense of transmission performance.
