Abstract
Disclosed in the present invention is a device and method for controlling an intelligent reflecting surface array. The device comprises a control voltage module, a voltage amplification module and a varactor module which are connected in sequence; the varactor module is embedded in a subunit structure of the intelligent reflecting surface array; the control voltage module is used for generating a high-precision low-amplitude analog control voltage signal and inputting same into the voltage amplification module; the voltage amplification module is used for receiving the low-amplitude analog control voltage signal inputted by the control voltage module, and amplifying and inputting the low-amplitude analog control voltage signal into the varactor module; the varactor module is used for receiving a high-amplitude analog voltage signal inputted by the voltage amplification module to realize the regulation and control of a varactor output capacitance value. The present invention can realize the independent continuous controllability of each subunit of the intelligent reflecting surface array without using a DA chip, so that the manufacturing costs are remarkably reduced while ensuring high precision of communication channel management.
