Abstract

The invention provides a radio frequency LPA Mid device, a radio frequency transceiving system and communication equipment, the radio frequency LPA Mid device is configured with a first low frequencytransmitting port and at least one receiving port used for connecting a radio frequency transceiver and four alternate transmitting ports used for connecting an antenna, the radio frequency LPA Mid device comprises a transmitting circuit connected with the first low frequency transmitting port, and is used for amplifying a plurality of low-frequency-band signals received by a first low-frequency transmitting port; a receiving circuit which is connected with the plurality of receiving ports and is used for amplifying the plurality of low-frequency-band signals received by the wheel emission port and outputting the amplified signals to the receiving ports; and switching circuits which are correspondingly connected with the transmitting circuit, the receiving circuit and the four alternate transmitting ports and are used for selectively conducting the radio frequency path between the transmitting circuit and any alternate transmitting port so as to support alternate transmission of any low-frequency-band signal among the four alternate transmitting ports, so that the integration degree of the radio frequency device can be improved, and the area is saved.

Description

technical field [0001] The present application relates to the field of radio frequency technology, in particular to a radio frequency L-PA Mid device, a 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. The communication frequency of 5G mobile communication technology is higher than that of 4G mobile communication technology. At present, major operators have put forward the functional requirements for 5G NR signals to support Sounding Reference Signal (SRS). In order to realize the SRS function of 5G NR low-band signals, the structure of its RF devices is relatively complicated and occupies a large area of ​​the substrate. . Contents of the invention [0003] The embodiment of the present application provides a radio frequency L-PA Mid device, a radio frequency transceiver system and commu...
