Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a storage medium, and a device for cooperative arrangement of a radio frequency power amplifier and a converter.
Background
Radio frequency power amplifiers (radio frequency power amplifiers for short) are important components of various wireless transmitters. In the front stage circuit of the transmitter, the radio frequency signal power generated by the modulation oscillation circuit is very small, and the radio frequency signal can be fed to an antenna to be radiated after sufficient radio frequency power is obtained through a series of amplifying-buffering stage, intermediate amplifying stage and final power amplifying stage. In order to obtain a sufficiently large radio frequency output power, a radio frequency power amplifier must be employed.
A DC/DC converter (simply referred to as DC/DC) is a voltage converter that converts an input voltage and then effectively outputs a fixed voltage. At present, the DC/DC converter is widely used in products such as mobile phones, MP3, digital cameras, portable media players, etc., and belongs to a chopper circuit in terms of circuit type classification.
In the mobile terminal, the DC/DC converter and the radio frequency power amplifier are all indispensable. The DC/DC converters and the radio frequency power amplifiers of many manufacturers are designed in an integrated mode, and work cooperatively inside a chip, but the chip in the integrated design is high in price, and meanwhile flexible design cannot be achieved.

The receiving power and the radio frequency power amplifier parameters under different frequency bands are in one-to-one correspondence and stored in advance, so that the radio frequency power amplifier parameters are conveniently searched.

After receiving the radio frequency power amplifier parameter setting instruction, the mobile terminal sets voltage parameters for the DC/DC converter, and then sets radio frequency power amplifier parameters for the radio frequency power amplifier. By establishing a relation between the radio frequency power amplifier and the DC/DC converter in advance, when the mobile terminal needs to set the radio frequency power amplifier parameters, the DC/DC converter is set to set the voltage parameters, and then the radio frequency power amplifier parameters are set.
