Radio-frequency assembly and special SPI data transmission method thereof

The invention discloses a radio-frequency assembly and a special SPI data transmission method thereof. The special SPI data transmission method is designed to meet the requirements for array element control and miniaturization. Dual-chip selection is used for array rank address selection, and accordingly under the condition that the array scale is large, chip selection signal lines are effectively reduced, and equipment complexity is reduced. The loading enabling control function is also added, and simultaneous amplitude-phase control over all the array elements is achieved. By means of the method, four-channel array element control as well as single-channel and two-channel array element control can be achieved, and applicability of the method is improved. 本发明公开了种射频组件及其专用SPI数据传输方法，该发明是为满足阵列阵元控制以及小型化要求，设计的专用SPI数据传输方法。本发明采用了双片选，用于阵列行列地址的选择，从而在阵列规模较大情况下，有效地减少了片选信号线，降低了设备复杂度。本发明同时增加了装载使能控制功能，实现了对阵列所有阵元的同时幅相控制。本发明不但可以实现四通道的阵元控制还可以实现单通道、双通道的阵元控制，增加了本发明的适用性。
