Abstract

The embodiment of the invention discloses a radio-frequency module, a transceiver and a method for switching control of the transceiver. The radio-frequency module comprises a first receiving amplification branch, a first receiving frequency mixer, a second receiving frequency mixer, a frequency mixing switching module and a control module, wherein the first receiving amplification branch is connected with the first receiving frequency mixer; the frequency of a local oscillation signal adopted by the first receiving frequency mixer is more than, less than or equal to that of a local oscillation signal adopted by the second receiving frequency mixer; and the control module is used for controlling the frequency mixing switching module to establish a connection between the first receiving amplification branch and the second frequency receiving mixer, or controlling the frequency mixing switching module to switch off the connection between the first receiving amplification branch and the second receiving frequency mixer. In the technical proposal provided by the embodiment of the invention, the radio-frequency module of the transceiver adopts an expandable framework, can expand the framework and switch working modes as required, and can adapt to various application scenes.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency module, a transceiver and a method for switching control of the transceiver. Background technique [0002] At present, the radio frequency modules corresponding to wireless base station transceivers tend to be multi-carrier. With the increase of the number of carriers, broadband transceivers are required to provide higher signal bandwidth, especially when the frequency spectrum is discontinuous or multiple equipment manufacturers share radio frequency In scenarios such as modules, higher requirements are placed on the signal processing bandwidth that the radio frequency module of the transceiver can provide. [0003] The architecture of existing transceivers mainly includes: 1T2R architecture, 2T2R architecture, 4T4R architecture, etc., wherein, the above-mentioned T refers to the number of channels that independently transmit signals under the same instan...
