本文讨论变容管控制的脉冲微波固态源的同步锁相环的应用,它用于必须重复建立锁定的雷达系统和某些型号的数字通信。特别重要的是镇定速度,而主要注意力放在低群延迟环路放大器的设计。这样用一阶特性获得最大入锁范围,本文描述了可调带宽大于10%的3GHz源的锁定性能并表示可获得20nS 范围的锁定时间。本文还说明脉冲形成期间可能触发源的相位并促使或者阻碍锁定的电平极底的泄漏信号能对环路的锁定性能产生显著的影响。
This article discusses the application of a varactor controlled pulsed microwave solid-state source to a synchronous phase locked loop, which is used in digital communications that must repeatedly establish a locked radar system and some models. Of particular importance is the speed of stabilization, with the main focus being on the design of low-group delay loop amplifiers. This maximizes the lock-in range with a first-order property. This article describes the lock-in performance of 3GHz sources with tunable bandwidths greater than 10% and indicates lockups in the 20 nS range. This article also illustrates that leakage signals that can trigger the phase of a source during pulse formation and cause or inhibit the locked level bottom can have a significant impact on the locking performance of the loop.
