Abstract

The present application relates to a radio frequency circuit and electronic equipment, the radio frequency circuit includes a radio frequency transceiver, a first transceiver, a second transceiver, a first filter, a second filter, a switch circuit, a first antenna and a second antenna . Wherein, the switch circuit is used to send the first signal transmitted by the radio frequency transceiver to the external device to the antenna corresponding to the output switch according to the input circuit, and send the second signal obtained from the input switch to the radio frequency according to the output circuit. transceiver. The input circuit and the output switch are determined according to the frequency of the first signal and the network mode corresponding to the radio frequency circuit, and the output circuit and the input switch are determined according to the frequency of the second signal, the The network mode and the receiving mode of the radio frequency circuit are determined. By adopting the application, the flexibility of signal transmission can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a radio frequency circuit and electronic equipment. Background technique [0002] With the rapid development of communication technology, electronic devices (such as mobile phones, etc.) support the non-standalone (NSA) mode of the fifth generation mobile communication technology (the 5th generation communication technology, 5G). The long-term evolution technology (Long Term Evolution, LTE) of the 4th generation mobile communication technology (4G), and the wireless air interface technology (New Radio, NR) that supports 5G. [0003] In the prior art, the radio frequency circuit in the NSA mode needs to support the radio frequency transceivers of LTE and NR respectively, and the radio frequency transceivers of LTE and NR need two antennas respectively, so four antennas are required. However, the size of the low frequency (Low Band, LB) antenna is too large, ...
