Abstract

The invention provides a radio frequency front-end circuit and electronic equipment. The radio frequency front-end circuit comprises a first receiving path connected with a transceiver, wherein the first receiving path comprises a first low-noise amplifier; a first filter used for filtering signals outside a first frequency band and signals outside a second frequency band respectively; a second filter; a first antenna; a first switch, wherein the first end of the first switch is connected with the first low-noise amplifier, and the second end of the first switch is connected with the first filter; a second switch, wherein the first end of the second switch is connected with the first antenna through a double-pole-double-throw switch, the second end of the second switch is connected with the first filter, the third end of the second switch is connected with the second filter, and the second filter is a filter used for filtering signals outside a third frequency band, or is a filter used for filtering signals outside the first frequency band and signals outside the third frequency band respectively. Through the first switch, the second switch and the first filter which are separated, switching of a radio frequency path can be realized, and the manufacturing cost of a whole machine is reduced.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a radio frequency front-end circuit and electronic equipment. Background technique [0002] At present, with the development of the fifth-generation mobile communication technology (5G for short), the peak rate of 5G NR can reach 20Gbps, and the increase in rate requires 5G to support 4*4MIMO technology. That is, for the N41 frequency band, four antennas are required, while the B41 frequency band of 4G Long Term Evolution (LTE) requires two antennas for the main receiver PRX and the diversity receiver DRX. A total of 6 antennas are required, but the mobile phone space is limited. This brings great challenges to the design of radio frequency and antenna architecture. [0003] In the existing Non-Standalone (NSA) mode, due to the same frequency of B41 and N41, antenna multiplexing can be realized and the number of antennas can be reduced, that is, a five-ant...
