Problems solved by technology
[0008] The embodiment of the present application provides a radio frequency circuit and electronic equipment, which can solve the problem that the multi-pole multi-throw switch is used in the prior art to ensure that the signal is switched on multiple antennas, but the insertion loss of the multi-pole multi-throw switch is large and expensive. The large size reduces the performance of the mobile terminal and increases the radio frequency power consumption of the mobile terminal

Description
technical field [0001] The application belongs to the technical field of communication, and in particular relates to a radio frequency circuit and electronic equipment. Background technique [0002] With the advancement of science and technology, users are increasingly dissatisfied with the status quo of communication needs, and 5G mobile terminals have emerged as the times require. At present, the 5G NR (new radio, new air interface) mobile communication network includes two networking modes: Non-standalone (NSA) and Standalone (SA). NSA relies on the existing LTE (Long Term Evolution, Long Term Evolution) network, anchors the control plane on the LTE network, and the user plane data is carried by the 5G NR network or jointly carried by the 5G NR network and the LTE network; the independent bearer of the SA is complete. The control panel and user plane independently provide communication services for users, but SA needs to deploy a new 5G end-to-end network, including acce...
