Abstract

The invention discloses a radio frequency circuit, a signal transmitting method and electronic equipment, and belongs to the technical field of communication. The radio frequency circuit comprises a radio frequency transceiver, a change-over switch, a first power amplifier, a second power amplifier, a first antenna and a second antenna, a first signal transmitting end and a second signal transmitting end of the radio frequency transceiver are both connected with the change-over switch, the change-over switch is also respectively connected with the first power amplifier and the second power amplifier, the first power amplifier is connected with the first antenna, and the second power amplifier is connected with the second antenna. In the embodiment of the invention, when the electronic equipment is far away from the base station and the transmitting power of the first power amplifier of the first signal cannot meet the communication requirement, the first signal is transmitted through the power amplifier and the second antenna which are originally used for transmitting the second signal, so that the transmitting power of the first signal can be effectively improved; therefore, the electronic equipment can reside in the network cell corresponding to the first signal.

Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to a radio frequency circuit, a signal transmitting method and electronic equipment. Background technique [0002] At present, when a terminal is registered on the NSA network, the LTE base station is used as the anchor point, and the maximum signal transmission power is generally only 23dbm. The main frequency bands used as the NSA anchor point are B1 / B3 and B39. When the terminal is far away from the LTE anchor point base station, Due to insufficient transmission power, the terminal will fall back from the 5G network to the 4G network, or even the 2G network; when the terminal is registered on the SA network, such as a network cell in the N1 or N3 frequency band, when the distance from the base station is far away, the terminal will also be affected by the transmission power. Not enough, causing the terminal to fall back from the 5G network to the 4G network, o...
