A radio frequency array control circuit and its control method

Abstract

The invention discloses a radio frequency array control circuit, which includes a control signal generation module, an information storage and conversion module and a load module. The information storage and conversion module includes an information storage module and an information conversion module. The load module includes an isolation and buffer module, a switch control module and a load circuit. The present invention can realize the maximum control degree of freedom for controlling each radio frequency array unit, and can greatly reduce the number of control lines. Compared with traditional methods, the control complexity can be reduced from N 2 Reduced to N, that is, for the common N×N square matrix, the traditional method is used for control. In order to achieve the greatest degree of control freedom, N 2 Control the control line one by one; and use the control array and method of the present invention to achieve the greatest degree of freedom of regulation and control only need N control lines to provide storage work state control information, N lines to provide load work state control information , a total of 2N control lines.

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
