Keithley's Making Measurements with Confidence CD, which is
available free of charge, is a collection of on-line seminars on
measurement methods. This CD offers practical and helpful techniques
for obtaining the most accurate and precise measurements possible.

Optimism Rampant at Long Beach MTT-S

Although sales are still relatively flat for many high-frequency
manufacturers, the general tone of exhibitors at last week's
Microwave Theory & Techniques Symposium (MTT-S) in Long Beach, CA
was optimistic. Several companies even mentioned direct sales orders
from attendees at the show. Most indicated that they expected
business to pick up during the second half of 2005, especially in
key areas of defense electronics and homeland security.

In terms of technology and products, ultrawideband (UWB) devices
made a strong showing at MTT-S, notably a series of UWB
system-on-chip (SoC) devices from M/A-COM ( http://nls.planetee.com/t?ctl=CEAD:FFCBF ).
Based on an advanced silicon-germanium (SiGe) process, the 24-GHz,
plastic-packaged transmitter and receiver SoCs target high-end
automotive radar systems (rather than the more competitive,
lower-frequency UWB data-communications applications).

As expected, the MTT-S featured scores of significant software
advances, along with new components (even involving some
"disruptive" technologies, such as that offered by Dielectric
Laboratories) and some impressive test instrument introductions. To
celebrate some of these new products, the next several issues of
this newsletter will include various highlights from the show, for
those who could not be there.

Broadcom Selects Fairchild PAM For Wi-Fi Reference Design

Fairchild Semiconductor announced at last week's MTT-S that its
4.9-to-5.9-GHz model RMPA5255 power amplifier module (PAM) had been
selected for use in Broadcom's single-chip and PCI Express Wi-Fi
reference designs. According to Brian Bedrosian, senior product line
manager for Broadcom's Home and Wireless Networking Business Unit,
"as manufacturers utilize new bus architectures and integrate Wi-Fi
capabilities into smaller devices, Broadcom is working with leaders
like Fairchild to develop solutions that meet the latest size, cost,
and performance requirements." More information on the RMPA5255 PAM
is available at the data-sheet link below.

Disruptive Technologies Spark Filters, Resonators

Dielectric Laboratories (Cazenovia, NY) unveiled what it calls its
"disruptive" technologies at last week's MTT-S. Leveraging expertise
in ceramic substrate materials, the firm has developed a
patent-pending high-quality-factor (high-Q) temperature-stable
cavity resonator. These high-Q resonators (Qs to 1500 at 2 GHz),
which are compatible with surface-mount packaging and chip-and-wire
assembly techniques, are available for single frequencies as high as
67 GHz with frequency tolerances as tight as 0.1 percent. Suitable
for microwave and millimeter-wave oscillators in automotive,
commercial, and military applications, the self-shielded resonators
feature high stability with temperature at a fraction of the size of
other resonator technologies. The company has also applied its
"disruptive" ceramic technology to the development of patent-pending
single- and multiple-pole cavity filters for microwave and
millimeter-wave applications.

Rohde & Schwarz Launches First Eight-Port VNA

In tune with the old American television comedy program "Eight Is
Enough," Rohde & Schwarz unveiled the industry's first eight-port
vector network analyzer at last week's MTT-S in Long Beach, CA.
Ideal for multiport and balanced component testing, the company's
model ZVT8 VNA has a reflectometer at each of its eight test ports
for simultanous testing on multiple components or components with
multiple ports. The analyzer covers a range of 300 kHz to 8 GHz with
+13 dBm minimum test signal power at each port and a dynamic range
of better than 120 dB.

CMOS Process Passes 13 GHz

Peregrine Semiconductor Corp. has announced that it has passed the
13-GHz mark with its UltraCMOS process technology, a frequency/speed
level once thought impossible for silicon CMOS semiconductors. The
company's model PE9308 prescaler, which is designed for space-based
and demanding military applications, is the first CMOS device to
operate at X-band and Ku-band frequencies. According to Jim Cable,
Peregrine's president and chief executive officer (CEO), "UltraCMOS
technology has broken the speed barrier long associated with
traditional CMOS processes." The prescaler consumes about one-tenth
the power of equivalent GaAs devices, at typically 25 mA current
from a +2.5-VDC supply.

AWR Releases cdma2000 Test Bench For VSS

Among the many major computer-aided-engineering (CAE) software
announcements at last week's MTT-S, Applied Wave Research (AWR) took
the wraps off a code-division-multiple-access 2000 (cdma2000) test
bench for the company's Visual System Simulator (VSS). The test
bench allows engineers to evaluate the impact of link impairments on
essential system performance parameters, including frame error rate
(FER), bit error rate (BER), and symbol error rate (SER). The
cdma2000 test bench consists of transmit and receive blocks and
support various frame sizes, data rates, and numbers of
communications channels, such as traffic channels, pilot channels,
and includes an orthogonal channel noise simulator (OCNS).

In other software news at MTT-S, Sonnet Software demonstrated one of
the industry's first cluster computer applications of its
electromagnetic (EM) simulation software, using a multiprocessor
rack-mount computer system to perform analyses on planar microwave
structures in mere minutes that once required hours or even days.

Cables Cut Loss To Zero

One of the more impressive transmission-line products introduced at
last week's MTT-S was the Zero dB coaxial cable assemblies from
Times Microwave Systems (Wallingford, CT). Suitable for fighter
aircraft and unmanned aerial vehicles (UAVs), the cable assemblies
seemingly defy the laws of physics by exhibiting no attenuation from
0.5 to 18.0 GHz. In reality, they incorporate wideband
monolithic-microwave-integrated-circuit (MMIC) gain blocks to
overcome the normal loss of the cable, with bias provided through
the termination connectors.

8. Book Review
Ultra Wideband Signals and Systems In Communications Engineering

Written by M. Ghavami, L. B. Michael, and R. Kohno, Ultra Wideband
Signals and Systems In Communications Engineering focuses on the
signal-processing aspects of UWB consumer communications systems,
rather than on UWB radar systems. It includes sections on generating
UWB waveforms, modeling indoor communications channels (since most
UWB communications systems are for short-range indoor applications),
UWB antennas and antenna arrays, and positioning and location
applications with UWB technology. The text concentrates on a basic
presentation of the technology, avoiding current debates over the
merits of the Intel versus Motorola approaches to UWB
