Abstract

The invention provides a radio frequency PA Mid device, a radio frequency system and a communication device. The radio frequency PA Mid device and a first transceiver circuit are used for receiving a first radio frequency signal through a first transmitting port, and carrying out the amplification and filtering of the received first radio frequency signal; a second transceiving circuit is used for receiving a second radio frequency signal through a second transmitting port and amplifying and filtering the received second radio frequency signal; and a multi-channel selection switch is used for selectively conducting a transmitting path between the first transmitting and receiving circuit and any antenna in-turn transmitting port as well as between the second transmitting and receiving circuit and any antenna in-turn transmitting port so as to support the function of in-turn transmitting of the dual-band detection reference signals among the antennas through the antenna in-turn transmitting ports, so that the insertion loss of the transmitting paths can be reduced, meanwhile, the occupied space of the radio frequency PA Mid device is also reduced, the cost is reduced, and the communication performance of the radio frequency system is also improved.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency PA Mid device, radio frequency 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. The communication frequency of 5G mobile communication technology is higher than that of 4G mobile communication technology. Generally, a plurality of discrete switches are set in the transmission path of the radio frequency system to support the radiation of the radio frequency signal between multiple antennas, which is costly and occupies a large area of ​​the substrate. Contents of the invention [0003] Embodiments of the present application provide a radio frequency PA Mid device, a radio frequency system, and communication equipment, which can save space, improve integration, and reduce costs. [000...
