A radio frequency module and a load mode switching method of the radio frequency module

Abstract

The embodiment of the invention discloses a radio frequency module and a load mode switch method thereof, avoids delay caused by the fact that after the change of a load is detected, corresponding load mode switch is carried out, and avoids the problem of excessive stresses or voltage drop in the process. The radio frequency module comprises a power source conversion unit, a load mode prediction unit and a radio frequency transmitting unit, wherein the load mode prediction unit is connected between the power source conversion unit and the radio frequency transmitting unit; the radio frequency transmitting unit is used for outputting a radio-frequency carrier signal; the load mode prediction unit is used for acquiring the radio-frequency carrier signal from the radio frequency transmitting unit, performs load mode prediction according to the radio-frequency carrier signal, and outputs the load control signal; and the power source conversion unit is used for acquiring a load control signal and performing load mode switch according to the load control signal.

Description

technical field [0001] The invention relates to the field technology of radio frequency module load efficiency, in particular to a radio frequency module and a load mode switching method of the radio frequency module. Background technique [0002] At present, for wireless time-division systems, including time-division multiple access (TDMA, TimeDivisionMultipleAccess) / time-division duplex (TDD, TimeDivisionDuplexing) standard wireless communication products, the load model of the radio frequency module is: 4 hours full load, 12 hours half load, 8 hours of light load; Among them, full load, half load, and light load refer to the load capacity of the electronic circuit, while light load is relative to full load, which means that the load rate is very high within the load range of the circuit. Small (for example, the load rate is below 30%); usually, the RF module has a light-load working condition in the full load range under normal working conditions, and improving the ligh...

Problems solved by technology

[0004] However, from the perspective of working principle, whether it is switching from light load to heavy load or from heavy load to light load, the signal can be detected only when the load changes, so that the state can be switched, and there must be a control lag link; then in In the process of switching from light load to heavy load, due to the delay in the working state or frequency for a period of time before entering the heavy load state, the power supply may be in light load mode when the switch is actually heavy load, which will cause Unstable states such as excessive stress or output voltage drop
