Frequency Sources, Low Noise, Microsecond-Switching

Various models of frequency synthesizers from 0.1-6400 MHz;
excellent specs for phase noise, switching speed & spurious outputs.
With thousands sold PTS gives priority to quality & reliability, 
reflected in a 3-yr. warranty. Best performance-to-price ratio for 
microsecond switching/low noise generators. Demos available. See 
website for technical specs; call one of our engineers to discuss 
customizing a unit.

In Search Of The All-Digital Receiver

Emerging high-speed analog-to-digital-converter (ADC) products such 
as the MAX19586 from Maxim Integrated Products (see below) call to 
mind a goal set by military designers during the beginning of the 
"GaAs revolution" and the MIMIC progran for an "all-digital" 
receiver. The concept was based on removing the "black-magic" RF 
components from a receiver and performing direct digitization of 
incoming signals from the antenna. Digital processing from that 
point on would reveal the necessary signal information on phase, 
amplitude, time of arrival, and other factors, depending on the type 
of military system.

With the availability of devices like the MAX19586 ADC, this type of 
receiver is one step closer to reality. Of course, as threat signals 
move far beyond the range of RF, and into the millimeter-wave range 
(Soviet radars), there is still room for RF processing and 
components. And still some ways to go before ADCs can handle every 
signal presented to them.

80-MSamples/s ADC Achieves 80-dB SNR 

Maxim Integrated Products (Sunnyvale, CA) announced their MAX19586, 
a 16-b, 80-MSamples/s analog-to-digital converter (ADC) capable of a 
signal-to-noise ratio (SNR) of 80 dB. The converter features a noise 
floor of -82 dB at full scale and spurious-free dynamic range (SFDR) 
of -96 dBc with a 10-MHz input signal. The ADC can handle input 
signals to beyond 170 MHz and pushes the limits on noise performance 
for a high-speed data converter.

Study Projects WLAN and WiMAX Opportunities

Research firm Forward Concepts recently announced their latest study 
on WLAN and WiMAX equipment and chip markets. The report, "Beyond 
Wi-Fi: 802.11n, VoWi-Fi & WiMAX," provides an analysis of worldwide 
equipment and chip markets. It provides detailed forecasts through 
2009 of all market segments, including Access Points (APs) and base 
stations (WiMAX), Network Interface Cards (NICs), Wireless Router 
Gateways (WRGs), and the chipsets enabling the entire WLAN and WiMAX 
networks. The report projects an increase in WLAN equipment 
shipments in 2005 by 6 percent, in spite of a drop in averaqe 
equipment selling price of 23 percent. For a copy of the 392-page 
resport, visit the Forward Concepts web site.

Taconic Begins Manufacturing Materials in Korea

Taconic (Petersburgh, NY) has announced the start of manufaturing 
their copper-clad base materials for RF and microwave 
printed-circuit boards (PCBs) in Cheonan, Korea. The move helps the 
company respond more quickly to growing demand in Asia for the 
high-frequency mateirals. By shifting some production from American 
and Irish facilities to this new Korean facility, the company holds 
to increase capacity and offer customs reduced lead times.

Free CD Contains Test Troubleshooting Guide

A tutorial CD titled "Interactive Test & Measurement Troubleshooting 
Guide: How to Avoid Common Measurement Errors," teaches users how to 
explore the symptoms and causes of common errors associated with 
measuring low-level signals. Users clock on any of five common 
measurements, including low voltage, low resistance, and low current 
measurements, and are presented with typical applications, error 
symptoms, likely causes, and tips for avoiding errors. The CD is 
free upon request from Keithley Instruments. To request a free copy, 
call (800) 688-9951 or visit the company's web site.

Report Shows Increase in Cellular CMOS

CMOS devices are gaining ground in mobile handsets, according to a 
report by iSuppli called "Different Modules for DIfferent Folks." 
The report notes increased use of CMOS power amplifier modules, 
antenna-switch modules, and zero-IF receiver modules. It points out 
the top suppliers and projects the overall growth of the 
mobile-handset market through 2009. For more information on the 
report, visit the iSuppli web site.

Hamilton Receives Joseph F. Keithley Award

The IEEE hasnamed Dr. Clark A. Hamilton as the recipient of the 2005 
IEEE Joseph F. Keithley Award in Instrumentation and Measurement. 
Hamilton, who is President and CEO of VNetrix (Boulder, CO), has 
received the award for his work on making the DC Josephson junction 
array voltage standard a practical reality. The award is named in 
memory of the founder of Keithley Instruments.
