摘要
阻抗控制是PCB设计中的一个重要环节。良好的阻抗控制可以保证信号传输的质量,因此射频电路中阻抗控制必不可少。对影响传输线阻抗控制的主要因素进行了讨论,介绍了阻抗控制计算的一般方法,重点分析了如何利用ADS momentum软件对GPS模块射频输入端进行阻抗控制的设计。
Impedance controlling is an important part for PCB design. Nice impedance controlling ensures the quality of signal transmission, so it is necessary to control impedance in radio -frequency PCB design. This article discusses the major influences on impedance controlling. Furthermore, the usual method of impedance controlling is introduced. Mainly, the design of controlling RF input impedance in GPS module with ADS momentum is analyzed.
