1998 Wireless Symposium/Portable by Design Show Guide

Following is a listing of the workshops and papers composing the technical program of the 1998 Wireless Symposium & Exhibition, sponsored by Microwaves & RF and Wireless Systems Design magazines, to be held February 9–13 in Santa Clara, CA. A listing of the sessions composing the technical program of the Portable by Design conference, which has been integrated this year with the Wireless Symposium, is also included.

MONDAY, February 9, 1998

8:30 am to 12:00 pm

Workshop K14: Battery Basics
This workshop develops the basis for total battery system management, including control of charge, discharge and storage modes, and how these modes affect system reliability. Important physical fundamentals will be reviewed along with how these cell attributes relate to the performance and reliability of the battery system. The electrical double-layer structure and mass-transport properties that dominate the battery system performance also will be reviewed. A control method will be described whereby the applied electromotive force optimizes the electrokinetic behavior of the charged particles to maximize the performance and reliability of the battery system.

8:30 am to 5:00 pm

Workshop K11: Working with the IrDA Serial Infrared Protocol
This infrared technology training class will examine different aspects of the IrDA standard, including the physical layer, link access protocol (IrLAP), link management protocol (IrLMP), tiny transport protocol (TinyTP), and serial and parallel port emulation (IrCOMM). The workshop will conclude with implementation and testing strategies.

Workshop K13: EMC Problems and Solutions for Portable Electronics
This workshop is directed at common electromagnetic compatibility (EMC) problems in portable electronic equipment and solutions for them. The session will begin with the physics of electromagnetic interference, emphasizing the frequency-amplitude time independence and dimensions (FAT-ID) approach to grounding and shielding as related to portable design. A number of case histories of EMC problems, along with how they were solved, will be presented.

Workshop K15: Wireless RF Circuit Design (Small-signal and Low Noise Amplifiers for Wireless Communications Systems)
This one-day course will cover small-signal amplifier design using bilateral S-parameter techniques and considering input/output impedance match, gain flatness, noise figure and component realizability. Since optimizing for minimum noise requires a sacrifice in gain and input match, noise-gain-match trade-offs will be considered with the help of graphical design tools. In addition, RF stability will be examined and various narrow- and broadband stabilization techniques will be evaluated.

Workshop K16: Measuring the Wireless Transmission Spectrum
This powerful workshop will provide comprehensive insights into different types of wireless signals, such as digitally modulated signals, EMI, RF interference, pulsed signals, high power signals, broadcast signals and television signals, and effective methods for measuring these signals with a spectrum analyzer. The course will explain the many different measurements that are possible on the signals themselves and within a given bandwidth.

Workshop K17: Active, Digital and RF Filter Design, Part I
This two-day course is the most comprehensive filter class available today for practicing engineers working in applications from microwave down to baseband frequencies. The first day covers digital signal processing and digital, micro and active filters, including fundamental concepts, time and frequency domains, and transfer functions. Examples of the application of these concepts to practical filters will be given. In addition, LC filters will be introduced. The second day will continue with LC filters and also will cover microstrip and machined filters for high frequency and wireless applications with emphasis on practical design issues. The course is aimed at engineers with little or moderate exposure to practical filter design.

Workshop K18: Wireless Made Simple, Part I
This tutorial-level course is ideal for technical managers and marketing professionals who need to know about RF and wireless technologies but don't want to suffer through lengthy and complex mathematical explanations. One day will be devoted to RF principles, systems and devices. The second day will highlight wireless systems at a block diagram level and provide insights into different modulation techniques, system functions (such as error correction and voice coding) and wireless markets.
