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 transceiver is connected with the radio frequency processing circuit. 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 and a first filter. The 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 antenna is used for receiving in a diversity manner in the first low-frequency band. The first filter is used for filtering frequency bands except the first low-frequency band. According to the embodiment of the invention, the reliability of an uplink signal can be ensured.

Description

Technical field [0001] This application relates to the technical field of mobile terminals, and in particular to a radio frequency system and electronic equipment. Background technique [0002] With the widespread application of a large number of electronic devices such as smart phones, smart phones can support more and more applications and more powerful functions. Smart phones are developing in a diversified and personalized direction and become an indispensable electronic product in users’ lives. . 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 4G scheme is relatively simple, including transmitting device, receiving device, switch and antenna. The transmitting device may include a low band (LB) transmitting module and a middle high band (MHB) transmitting module, and the receiving device may include a primary receive (PRX) module a...
