Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a radio frequency circuit, a control method, and electronic equipment. Background technique [0002] In the existing 5G networking mode, non-independent networking (Non-Stand Alone, NSA) dual-connection mode is used to form a network, and the long-term evolution (Long Term Evolution,) LTE network coverage capability is used to provide signaling interaction, and the new air interface (NewRadio, NR) only provides data plane bearing for capacity enhancement. [0003] The existing NSA network feedback to the hardware design side requires two radio frequency channels to transmit simultaneously. Each of the two radio frequency channels includes a power amplifier (Power Amplifier, PA), and each PA is powered by an independent power module, resulting in power supply costs. Higher, the power module occupies a larger area. Contents of the invention ...
