Abstract

The embodiment of the invention discloses a radio frequency system and electronic equipment. The radio frequency system comprises a radio frequency transceiver, a radio frequency processing circuit, aselector switch module, a first antenna, a second antenna, a third antenna and a fourth antenna; the radio frequency processing circuit comprises a first transmitting module, a second transmitting module, a first receiving module, a second receiving module, a first duplexer, a second duplexer, a first selection switch and a first filtering module. A radio frequency system works in a non-independent networking mode; the first antenna is used for transmitting a first low-frequency band and receiving a main set of the first low-frequency band; the second antenna is used for transmitting in a second low-frequency band and receiving in a main set of the second low-frequency band; the third antenna is used for receiving in a diversity manner in the second low-frequency band, the fourth antennais used for receiving in a diversity manner in a first low-frequency band, and the first filter is used for filtering frequency bands except the first low-frequency band. According to the embodiment of the invention, the system can ensure the reliability of an uplink signal.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, 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 fourth generation (4th Generation, 4G) mobile communication systems 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 middle high frequency (middle high band, MHB) transmitting module, and the receiving device may include a primary receive (primary receive, PRX) module and a...
