Radio frequency array control circuit and control method thereof

Abstract

The invention discloses a radio frequency array control circuit which comprises a control signal generation module, an information storage and conversion module and a load module, wherein the information storage and conversion module comprises an information storage module and an information conversion module. The load module comprises an isolation and buffer module, a switch control module and aload circuit. According to the invention, the maximum regulation and control degree of freedom for controlling each radio frequency array unit can be realized, and the number of control lines can be greatly reduced. Compared with a traditional method, the method has the advantages that the control complexity can be reduced to N from N2, that is, for a common N * N square matrix, the traditional method is used for controlling, and N2 control lines are needed for controlling the square matrix in a one-to-one correspondence mode to achieve the maximum regulation and control freedom degree; by using the control array and the control method provided by the invention, only N control lines are required to provide storage working state control information and N lines are required to provide load working state control information for realizing the maximum regulation degree of freedom, and 2N control lines are provided in total.

Description

technical field [0001] The invention relates to the field of radio frequency arrays, in particular to a radio frequency array control circuit and a control method thereof. Background technique [0002] The feeding method of the RF array unit structure loaded on the existing adjustable RF array is relatively complicated, mainly using thin metal wires to connect to the bias voltage interface, and adjusting the working state of the RF array unit by controlling the voltage supplied by the thin metal wires . [0003] Based on this method, there are two main control ideas. One is that because the radio frequency array is often symmetrical, multiple units can be controlled by one control line. This method has relatively few control lines, but the radio frequency array The adjustable degree of freedom will be limited; the second is to control each radio frequency array unit by a control line. This method can achieve the largest adjustable degree of freedom of the radio frequency ar...

[0002] The feeding method of the RF array unit structure loaded on the existing adjustable RF array is relatively complicated, mainly using thin metal wires to connect to the bias voltage interface, and adjusting the working state of the RF array unit by controlling the voltage supplied by the thin metal wires

[0003] Based on this method, there are two main control ideas. One is that because the radio frequency array is often symmetrical, multiple units can be controlled by one control line. This method has relatively few control lines, but the radio frequency array The adjustable degree of freedom will be limited; the second is to control each radio frequency array unit by a control line. This method can achieve the largest adjustable degree of freedom of the radio frequency array, but when the adjustable radio frequency array is more complicated , the number of control lines is too much, which not only brings a huge challenge to the number of ports of the control system (such as MCU, FPGA), but also brings great difficulties to the programming of the control algorithm
