Abstract

The invention provides a radio frequency L-PA Mid device, a radio frequency transceiving system and a communication device, the radio frequency L-PA Mid device is configured with at least one transmitting port, a plurality of receiving ports and at least one antenna port, and the radio frequency L-PA Mid device comprises a transmitting module used for receiving a plurality of low-frequency signals and amplifying and filtering the received low-frequency signals; a plurality of first ends of the first switch unit are respectively and correspondingly connected with the transmitting modules, and a second end of the first switch unit is connected with an antenna port; the receiving module is respectively connected with the plurality of first ends of the first switch unit and each receiving port, the receiving module comprises at least one low-noise amplifier, and the filtered low-frequency signal is amplified by each low-noise amplifier and then outputs at least one low-frequency signal; the first control unit is used for adjusting the gain coefficient of the low-noise amplifier so as to reduce the cascade noise coefficient of the at least one low-frequency signal receiving path, and then the sensitivity of the radio frequency transceiving system can be improved.

Description

technical field [0001] The application relates to the field of radio frequency technology, in particular to a radio frequency L-PA Mid device, radio frequency transceiver system and communication equipment. Background technique [0002] With the development and progress of technology, in order to meet the increasing demands of various network standards and at the same time solve the problem of tight PCB layout, the high integration and miniaturization of devices has become a development trend. From Phase 2 products that only support single-band at the beginning, to Phase 7 products that support the integration of various standards, the integration level of devices is getting higher and higher, and the package size of devices is getting smaller and smaller. A low-frequency power amplifier module with a built-in low-noise amplifier is defined in the general 2G, 3G or 4G architecture design. However, when this module is applied to a radio frequency transceiver system to receive...
