Problems solved by technology

With the increase of communication network standards, terminal equipment must support communication requirements under various network standards of 2G, 3G, 4G, and 5G; limited by the size constraints of terminal equipment, the space of the motherboard PCB has not been increased due to the increase in demand. Substantial increase, which will lead to very tight space layout and wiring of the motherboard PCB
[0003] In order to support ENDC, it is necessary to use additional multimode multiband power amplifier (MMPA, MultimodeMultiband Power Amplifier Module) devices, which will undoubtedly add to the problem of tight space layout and wiring, and also increase the complexity of PCB layout and wiring. increased costs

Abstract

The invention discloses a radio frequency front-end device, a radio frequency transceiving system and communication equipment, which are used for a diversity antenna radio frequency link or a main antenna and diversity antenna radio frequency link, and can support a non-independent networking mode without externally hanging a multi-mode multi-frequency power amplifier device, thereby improving the integration level and reducing the occupied mainboard area. Moreover, the integration level of the device is improved, so that the cost is reduced; moreover, through integration, wiring of power supply, transmission control and the like is reduced, the complexity of single board layout is reduced, and the performance of a radio frequency transceiver system and communication equipment is improved.

Description

technical field [0001] This application relates to but not limited to radio frequency technology, especially a radio frequency front-end device, radio frequency transceiver system and communication equipment. Background technique [0002] With the development and progress of technology, 5G mobile communication technology has gradually begun to be applied to electronic devices. With the increase of communication network standards, terminal equipment must support communication requirements under various network standards of 2G, 3G, 4G, and 5G; limited by the size constraints of terminal equipment, the space of the motherboard PCB has not been increased due to the increase in demand. A substantial increase, which will lead to very tight space layout and wiring of the motherboard PCB. [0003] In order to support ENDC, it is necessary to use additional multimode multiband power amplifier (MMPA, MultimodeMultiband Power Amplifier Module) devices, which will undoubtedly add to th...
