Abstract

This application proposes a radio frequency system and electronic equipment, including a radio frequency transceiver, a radio frequency processing circuit, a switch module, a first antenna and a second antenna; the radio frequency processing circuit includes a first transmitting module, a diversity receiving module , a first triplexer, a directional coupler, a second transmitting module, a main set receiving module, and a second triplexer; when the radio frequency system is in a non-independent networking mode, the first antenna is used for The transmission of the first low frequency band, the diversity reception of the combination of the first low frequency band and the second low frequency band, the second antenna is used for the transmission of the second low frequency band, the first low frequency band and the second low frequency band The main receiver of two low-frequency frequency bands combined. Two triplexers and combined radio frequency circuit designs can be used, and special devices can be used for combined antenna design, so that two antennas can complete dual low-band non-independent networking, which greatly improves the dual low-band non-independent networking in electronic equipment. versatility on.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency system and electronic equipment. Background technique [0002] With the popularization and application of electronic devices such as smart phones, more and more applications can be supported by smart phones, and the functions are becoming more and more powerful. . Electronic devices in the 4th Generation (4G) mobile communication system generally adopt a single-antenna or dual-antenna radio frequency system architecture. The radio frequency framework of the 4G solution is relatively simple, including transmitting devices, receiving devices, switches and antennas. Wherein, the transmitting device may include a low frequency (Low Band, LB) transmitting module and a high frequency (Middle High Band, MHB) transmitting module, and the receiving device may include a primary receive (Primary Receive, PRX) module and a diversity receive (Diversity R...
