High-precision power control radio frequency channel design and calibration method

Abstract

The invention relates to a high-precision power control radio frequency channel design and calibration method. The method comprises the following steps: constructing a high-precision power control radio frequency channel; the high-precision power control radio frequency channel comprises a microcontroller, an up-conversion unit, a down-conversion unit and a data storage unit; a microcontroller receives frequency information and attenuation information input by an external program, reads a corresponding power control instruction from a data storage unit according to the frequency information and the temperature and attenuation information of a high-precision power control radio frequency channel, and sends the power control instruction to an up-conversion unit and a down-conversion unit respectively; and performing power control of the high-precision power control radio frequency channel according to the power control instruction through power control chips in the up-conversion unit and the down-conversion unit respectively. By adopting the method, the power control precision of the radio frequency channel in different environments can be improved.
