指南和在线研讨会
将高性能RF信号链集成至更小空间的解决方案
本次在线研讨会将介绍RF IC技术集成的现状，重点讨论非手机无线设备设计人员所面临的挑战，他们努力在更小的空间中实现更多的功能，有时候还要面临必须采用可在多频率下重复使用的宽带收发器等棘手问题。数字信号的射频发射和接收基本原理
由于大多数现代收发器都会发射和接收数字调制的数据，因此数字调制是RF设计师的重要课题。本次在线研讨会是ADI公司陆续推出的“设计基础”系列研讨会之一，旨在介绍数字调制的各种挑战及其解决方案。初学者可以借助本次在线研讨会认识这项重要通信标准，而资深RF设计师则可借此了解该领域的最新情况。与RF器件接口
对于任何成功的RF设计，接收机和发射机内各级的接口是最重要的事情之一。如果电路各级之间的连接不当，谐波、不良衰减和其它缺陷就会凸显出来。本研讨会将介绍有助于实现RF电路最高性能的最佳做法。调制器/解调器技术文章

滤波器
Analog Filter Wizard 2.0
The Analog Filter Wizard™ helps you design a low-pass, high-pass, band-pass or band-stop filter with actual op amps. It then simulates the filter’s performance with these op amps in real time. You can ask the tool to optimize for power, noise, or voltage range, and it will pick op amps and passive components appropriately. Or you can adjust the components manually yourself.
