Agilent AN 154 S-Parameter Design Application Note S参数的设计与应用 The need for new high-frequency, solid-state circuitdesign techniques has been recognized both by microwaveengineers and circuit designers. These engineersare being asked to design solid state circuitsthat will operate at higher and higher frequencies.The development of microwave transistors andAgilent Technologies’ network analysis instrumentationsystems that permit complete network characterizationin the microwave frequency rangehave greatly assisted these engineers in their work.The Agilent Microwave Division’s lab staff hasdeveloped a high frequency circuit design seminarto assist their counterparts in R&D labs throughoutthe world. This seminar has been presentedin a number of locations in the United States andEurope.From the experience gained in presenting this originalseminar, WE have developed a four-part videotape, S-Parameter Design Seminar. While the technologyof high frequency circuit design is everchanging, the concepts upon which this technologyhas been built are relatively invariant.The content of the S-Parameter Design Seminar isas follows:

This book evolved over the past ten years from a set of lecture notes developed while teaching the undergraduate Algorithms course at Berkeley and U.C. San Diego. Our way of teaching this course evolved tremendously over these years in a number of directions, partly to address our students' background (undeveloped formal skills outside of programming), and partly to reect the maturing of the eld in general, as WE have come to see it. The notes increasingly crystallized into a narrative, and WE progressively structured the course to emphasize the story line implicit in the progression of the material. As a result, the topics WEre carefully selected and clustered. No attempt was made to be encyclopedic, and this freed us to include topics traditionally de-emphasized or omitted from most Algorithms books.

In this paper, WE discuss efficient coding and design styles using verilog. This can beimmensely helpful for any digital designer initiating designs. Here, WE address different problems rangingfrom RTL-Gate Level simulation mismatch to race conditions in writing behavioral models. All theseproblems are accompanied by an example to have a better idea, and these can be taken care off if thesecoding guidelines are folloWEd. Discussion of all the techniques is beyond the scope of this paper, hoWEver,here WE try to cover a few of them.

WE would like to WElcome you as a user of the Allegro CX, a rugged, handheld fi eld PC for data collection. Developed with the input of data collection professionals worldwide, the Allegro CX is adaptable and versatile for use in a wide variety of data collection environments. The Allegro CX continues to utilize our ergonomic, lightWEight design that is standard in our line of Allegro Field PCs. This design makes your Allegro easy to use for extended periods while moving to and from data collection sites in the fi eld.

Abstract: This application note presents an overview of electronic margining and its value in detectingpotential system failures before a product ships from the factory. It is a calibration method that effectivelypredicts and allows adjustments to improve product quality. Margining also can be used to sort productsinto performance levels, allowing premium products to be sold at premium prices. WE discuss thedownside of sorting and suggest alternative ways to segregate products.

ACPR (adjacent channel poWEr ratio), AltCPR (alternatechannel poWEr ratio), and noise are important performancemetrics for digital communication systems thatuse, for example, WCDMA (wideband code division multipleaccess) modulation. ACPR and AltCPR are bothmeasures of spectral regrowth. The poWEr in the WCDMAcarrier is measured using a 5MHz measurement bandwidth;see Figure 1. In the case of ACPR, the total poWErin a 3.84MHz bandwidth centered at 5MHz (the carrierspacing) away from the center of the outermost carrier ismeasured and compared to the carrier poWEr. The resultis expressed in dBc. For AltCPR, the procedure is thesame, except WE center the measurement 10MHz awayfrom the center of the outermost carrier.

Abstract: How can an interface change a happy face to a sad face? Engineers have happy faces when an interface works properly.Sad faces indicate failure somewhere. Because interfaces betWEen microprocessors and ICs are simple—even easy—they are oftenignored until interface failure causes sad faces all around. In this article, WE discuss a common SPI error that can be almostimpossible to find in a large system. Links to interface tutorial information are provided for complete information. Noise as a systemissue and ICs to minimize its effects are also described.

In each step the LZSS algorithm sends either a character or a <position, length> pair. Among these, perhaps character "e" appears more frequently than "x", and a <position, length> pair of length 3 might be commoner than one of length 18, say. Thus, if WE encode the more frequent in feWEr bits and the less frequent in more bits, the total length of the encoded text will be diminished. This consideration suggests that WE use Huffman or arithmetic coding, preferably of adaptive kind, along with LZSS.

This software aims to create an applet and panel tools to manage a wireless interface card, such as IEEE 802.11 cards. The development will focus on Linux, as this is the most accessible platform, but will expand as WE get access to more platforms
