Abstract

The invention discloses a radio frequency component and a special SPI data transmission method thereof. The invention is a special SPI data transmission method designed to meet the requirements of array element control and miniaturization. The present invention adopts double chip selection for selection of array row and column addresses, thereby effectively reducing chip selection signal lines and equipment complexity when the array scale is large. The invention also adds a loading enabling control function, and realizes simultaneous amplitude and phase control of all array elements. The present invention can realize not only four-channel array element control but also single-channel and double-channel array element control, which increases the applicability of the present invention.

Description

technical field [0001] The invention relates to a radio frequency component and its special SPI interface protocol in the field of array beam control. Especially in the case of a large array, a radio frequency component and its dedicated SPI interface protocol are designed to meet the requirements of miniaturization. Background technique [0002] At present, the SPI interface protocol adopted by radio frequency components in the field of array beam control generally only supports real-time data exchange of single-channel array elements and detection of working status of array elements, and the addressing of radio frequency components is performed through single chip selection. In the application, high-speed and real-time data exchange is realized between the sub-array and the array component units through SPI, and the detection of the components is completed at the sub-array level, so that the wave control system can monitor the entire array. The failure rate of the array u...
