Abstract

The application discloses a radio frequency circuit, a signal transmitting method and electronic equipment, which belong to the technical field of communication. The radio frequency circuit includes: a radio frequency transceiver, a switch, a first power amplifier, a second power amplifier, a first antenna and a second antenna; the first signal sending end and the second signal sending end of the radio frequency transceiver are connected to The switch is connected, and the switch is also connected to the first power amplifier and the second power amplifier respectively, the first power amplifier is connected to the first antenna, and the second power amplifier is connected to the second antenna. In the embodiment of the present application, when the distance between the electronic device and the base station is relatively long, and the transmission power of the first power amplifier of the first signal cannot meet the communication requirements, the first signal is passed through the power amplifier originally used to transmit the second signal and the second power amplifier. The transmission by the two antennas can effectively increase the transmission power of the first signal, so as to ensure that the electronic device can reside in the network cell corresponding to the first signal.

Description

Technical field [0001] The present application belongs to the field of communication technology, specifically relates to a radio frequency circuit, signal transmission method and electronic equipment. Background [0002] At present, when the terminal is registered in the NSA network, the LTE base station as the anchor, its signal transmission power is generally only 23dbm, as the main frequency band of the NSA anchor is B1 / B3 and B39, when the terminal is far away from the LTE anchor 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 in the SA network, such as the network cell in the N1 or N3 band, when it is far away from the base station, it will also cause the terminal to fall back from the 5G network to the 4G network or even the 2G network due to insufficient transmission power.
