基于AD936X超宽带可重构信道的快速跳频设计

Fast Frequency Hopping Design based on AD936X Ultra-Wideband Reconfigurable Channel

为了实现战术电台硬件形态统一化,为战术无线电台未来向软件化平滑过渡提供支撑,基于AD936X芯片设计了一个全新的通用性强的超宽带可重构信道,并使用该信道进行快速跳频设计。与传统上战术通信电台收发通道都采用超外差架构(AN/PRC-117G、AN/PRC-158)不同,本设计根据不同的应用场景(如手持、背负和车载式设备等),在发射端(TX)采用了直接正交调制架构,接收端(RX)采用超外差架构。另外,在本设计中,可重构信道重点应用了AD936X的快速锁频(FAST LOCK)特性,这方面的应用尚未在以往相关应用文献中提及。

To achieve hardware standardization of tactical radios and support a seamless transition to software-defined radios in the fiuture,this study presents a novel and versatile ultra-wideband reconfigurable channel based on the AD936X chip.The proposed channel is specifically designed for rapid frequency hopping.Unlike conventional tactical communication radios,such as AN/PRC-117G and AN/PRC-158,which employ superheterodyne architecture,the proposed design adopts direct quadrature modulation architecture at the transmitter to cater to diverse application scenarios,including handheld,backpack,and vehicular devices.Meanwhile,the receiver still utilizes superheterodyne architecture.Moreover,this research emphasizes the utilization of the AD936X's fast lock feature,which has not been previously addressed in the relevant literature.
