Abstract

The invention reveals a TD_LTE power detection module, and the module is used for the receiving and transmitting control and switching of communication equipment in mobile communication. The module comprises an uplink numerical control attenuation circuit, an uplink power detection circuit, a control circuit, a switching control tube, a downlink power detection circuit, and a downlink numerical control attenuation circuit. The uplink power detection circuit enables the detected uplink power level to be outputted to the control circuit, and the control circuit controls the attenuation quantity of the uplink numerical control attenuation circuit according to the uplink power level, and also controls the switching control tube to switch uplink and downlink radio frequency channels. In addition, the control circuit controls the attenuation quantity of the downlink numerical control attenuation circuit and the switching control of the switching control tube according to a downlink power level detected by the downlink power detection circuit. The invention also reveals a switching control method and the communication equipment. The module achieves the switching control of the TD_LTE communication equipment in a mode of power level detection, achieves the control of the digital attenuation quantity, is simple in circuit, and is low in cost.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a TD_LTE power detection module, a switch control method and a communication device that realize switchover by detecting signal power levels. Background technique [0002] As the 3G industry gradually steps into a climax in the world, LTE (Long Term Evolution, Long Term Evolution), which shoulders the evolution from 3G to 4G, is currently experiencing a critical period of development. [0003] TD-LTE (TimeDivisionLongTermEvolution, Time Division Long Term Evolution) is an evolution technology of TD-SCDMA (TimeDivision-Synchronous Code Division Multiple Access, Time Division Synchronous Code Division Multiple Access). more and more widely. [0004] The TD-LTE standard is a time-division duplex mode. The uplink signal and the downlink signal share the same frequency band. The uplink and downlink are distinguished through time-division multiplexing technology...
