摘要

本文介绍了一种适用于x波段的微型化宽带MEMS鉴相器，并在此基础上设计了一种新的锁相环系统。采用电容式负载的小型化方法，实现了体积缩小60%。测量的s参数显示x波段回波损耗S11小于- 15 dB。通过实验验证了相位检测的宽带特性。研究了鉴相器的温度效应。建立了考虑温度补偿的集成锁相环电路模型。通过仿真验证了该锁相环在跟踪和同步方面的有效性。

Research of a Miniaturized Broadband Mems Phase Detector and its Temperature Effect for Application in Phase-Locked Loops

This paper presents the miniaturization of a broadband MEMS phase detector for X-band application and a new phase-locked loop system based on it. Miniaturization approach of capacitive loading is adopted and a size-reduction of 60% is achieved. Measured S-parameter shows return loss S11 smaller than −15 dB over X-band. Broadband property of phase detection is also verified through experiments. Temperature effect of the phase detector is studied. An integrated PLL circuit model is established with temperature compensation incorporated. Validity of the PLL is confirmed by simulation with respect to tracking and synchronization.
