摘　　要：通过对模拟锁相环性能进行了理论分析和仿真实验,并在100 MHz帧速率上完成了电路实验,验证了采用模拟锁相环形式实现超宽带同步能够降低IR-UWB接收机的复杂度,证明此UWB射频同步接收机机能实现快速的捕获,并在数据段的长连"0"在不超过5个帧周期条件下,仍然可以保证采样时钟偏移满足精度要求,是一种简单而又实用的超宽带同步方法。The complexity of IR-UWB receiver can be reduced by using analog pll format to realize synchronization of UWB. It was proved through the theoretical analysis and the simulation test, and an experiment in circuit with the frame frequency of 100 MHz. The IR-APLL can realize the speediness capture, and can ensure that the excursion of sampling clock to meet the precision requirement - in the condition of series of ＂0＂ in the data segment is no longer than 5 frame periods. It is a simple and practical way to realize the synchronizing of UWB communication system.
