Rf And Microwave Power Amplifier Design（2005）

The Main objective of this book is to present all the relevant informationrequired for RF and micro-wave power amplifier design includingwell-known and novel theoretical approaches and practical design techniquesas well as to suggest optimum design approaches effectively combininganalytical calculations and computer-aided design. This bookcan also be very useful for lecturing to promote the analytical way ofthinking with practical verification by making a bridge between theoryand practice of RF and microwave engineering. As it often happens, anew result is the well-forgotten old one. Therefore, the demonstrationof not only new results based on new technologies or circuit schematicsis given, but some sufficiently old ideas or approaches are also introduced,that could be very useful in modern practice or could contributeto appearance of new ideas or schematic techniques.

軌道交通系統中列車定位技術

闡述了軌道交通列車定位技術。介紹了在軌道交通系統中列車定位技術的功能，國內外軌道交通中主要采用的列車定位方法，重點論述了幾種主要定位技術，并從定位精度、閉塞制式、維護投資成本、抗干擾等方面進行分析比較。提出目前軌道交通定位技術應綜合運用，取長補短，多種方法相互融合，才能滿足軌道交通中對安全可靠性的要求。 Abstract: Rail train positioning technology is described. The paper introduces the funetions of the train positioning technology in the rail transit system， the Main methods of train positioning do mestic and international rail， and focuses on several key methods， analyzes and compares from the positioning accuracy， block system, Maintenance and investment cost， interference and so on， suggested that the current rail positioning technology should be integrated use of positioning method of meriging， learn from each other， to meet the reliability requirements of rail safety.

orcad無法輸出網表問題解決方法

ORCAD在使用的時候總會出現這樣或那樣的問題…但下這個問題比較奇怪…在ORCAD中無法輸出網表…彈出下面的錯誤….這種問題很是奇怪…Netlist Format: tango.dllDesign Name: D:\EDA_PROJECT\PROTEL99SE\YK\SV3200\Main.DSNERROR [NET0021] Cannot get part.[FMT0024] Ref-des not found. Possible Logical/Physical annotation conflict.[FMT0018] Errors processing intermediate file找了一天沒找到問題…終于在花了N多時間后發現問題所在…其實這個問題就是不要使用ORCAD PSPICE 庫里面的元件來畫電路圖…實際中我是用了PSPICE里面和自己制作的二種電阻和電容混合在一起…就會出現這種問題…

MSP430之裸奔框架C++程序源碼

本程序主要表現了C++多文件系統的MCU構建方法,任何支持C++的MCU/ARM/DSP都可用此法構建。特別要注意變量的重復定義問題: 最好每個C/CPP文件包含與自己同名的H頭文件,在其H頭文件中再包含一個中間起橋梁作用的H頭文件,我一般喜歡Main.h 變量或函數要在C/CPP中定義，絕對不要在H頭文件中定義! 但一定要在H頭文件中用extern加變量或函數聲明。

pci e PCB設計規范

This document provides practical, common guidelines for incorporating PCI Express interconnect layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10- layer or more server baseboard designs. Guidelines and constraints in this document are intended for use on both baseboard and add-in card PCB designs. This includes interconnects between PCI Express devices located on the same baseboard (chip-to-chip routing) and interconnects between a PCI Express device located “down” on the baseboard and a device located “up” on an add-in card attached through a connector. This document is intended to cover all major components of the physical interconnect including design guidelines for the PCB traces, vias and AC coupling capacitors, as well as add-in card edge-finger and connector considerations. The intent of the guidelines and examples is to help ensure that good high-speed signal design practices are used and that the timing/jitter and loss/attenuation budgets can also be met from end-to-end across the PCI Express interconnect. However, while general physical guidelines and suggestions are given, they may not necessarily guarantee adequate performance of the interconnect for all layouts and implementations. Therefore, designers should consider modeling and simulation of the interconnect in order to ensure compliance to all applicable specifications. The document is composed of two Main sections. The first section provides an overview of general topology and interconnect guidelines. The second section concentrates on physical layout constraints where bulleted items at the beginning of a topic highlight important constraints, while the narrative that follows offers additional insight.
