技术资料 LQFP,TQFP,QFP,CQFP封装尺寸表
Low Profile Quad Flat Pack (LQFP) packages provide the same benefit of the metric QFP packages, but are thinner (body thickness of 1.4mm) and have a standard lead-frame footprint (2.0mm lead footprint). LQFPs help to solve issues such as increasing board density, die shrink programs, thin end-produc ...

模拟电子 正确的混合信号设计印刷电路板(PCB)的接地
Abstract: This tutorial discusses proper printed-circuit board (PCB) grounding for mixed-signal designs. Formost applications a simple method without cuts in the ground plane allows for successful PCB layouts withthis kind of IC. We begin this document with the basics: where the current flows. Lat ...
无线通信 无线技术指南
Radio frequency (RF) can be a complex subject to navigate, but it does not have to be. If you are just getting started with radios or maybe you cannot find that old reference book about antenna aperture, this guide can help. It is intended to provide a basic understanding of RF technology, as well a ...
