Hard To Argue With WiMAX Forum

Questions regarding WiMAX as a broadband services solution are no
longer "if" but more "when" and "how large a market." Generally, when
a entire industry gets behind a particular standard, as was the case
with IEEE 802.11, products are sold. The WiMAX Forum
(www.wimaxforum.org) is that industry spark for WiMAX, bringing
companies together with a common goal of driving the market through
products that work seamlessly together. The nonprofit organization
promises that WiMAX Forum certified products will be fully
interoperable and support wireless metropolitan area networks (MANs)
for broadband services.

By organizing its interoperability PlugFests (see News item #5), the
WiMAX Forum provides equipment suppliers and test equipment developers
an open environment to test compatibility. In doing so, the WiMAX
Forum helps speed products to market, and helps customers feel
confident that those products will interoperate properly. Admittedly,
the mobile portion of WiMAX may find more difficult market penetration
than the fixed version of WiMAX (that "last mile" for broadband
services). Still, the list of players involved in the WiMAX Forum's
second mobile PlugFest is impressive. Hard to argue that these
companies won't make WiMAX a success, based on their past histories.

Research Shows Rapid Growth In RFID

Research firm IDTechEx predicts that 1.71 billion
radio-frequency-identification (RFID) tags will be sold in 2007, with
a total RFID market size (including software and integration) of $4.96
billion. The largest part of the market will be in RFID cards, with
the non-card segment projected to be $1.97 billion globally. Excluding
cards, 58.4 percent of the market in 2007 will be in the US and 33
percent in Europe. The report, "RFID Forecasts, Players and
Opportunities 2007-2017," authored by IDTechEX Chief Executive Officer
(CEO) Raghu Das, projects that the RFID market will rise to more than
$27 billion by 2017.

Skyworks Shows WCDMA Modules At 3GSM

Skyworks Solutions announced new additions to its Intera(TM) line of
front-end modules at this week's 3GSM World Congress 2007 in
Barcelona, Spain. Developed for wideband-code-division-multiple-access
(WCDMA) applications in PCS bands I, II, IV, V, and VI, the compact
modules are designed to extend battery life and simplify integration
with virtually any baseband architecture. The WCDMA FEMs support high
speed uplink packet access (HSUPA), high speed downlink packet access
(HSDPA), and feature a built-in power coupler and detector. They also
include the company's patent-pending bulk-acoustic-wave (BAW) filter
technology. Model SKY77433 for Band I is a fully matched 16-pin,
full-duplex FEM in a small and efficient 4 x 7 mm package for
universal mobile telecommunications systems (UMTS) in Europe and Asia.
Model SKY77434 for Band II is a 4 x 7 mm FEM for U.S. PCS
applications. Model SKY77435 for Band IV is a 4 x 7 mm FEM for
advanced wideband systems (AWS), otherwise known as the Federal
Communications Commission (FCC) Auctioned Spectrum. Finally, model
SKY77436 for Band V is a 4 x 7 mm FEM for the US cellular market with
Band VI covered for Japan.

Another company making news at the 3GSM World Congress 2007 in
Barcelona was ANADIGICS, announcing that it had expanded its line of
WiMAX power amplifiers (PAs) with the introduction of the AWN6423 for
mobile WiMAX. In support of the IEEE 802.16e-2005 standards, the new
PA operates in the 2.5 to 2.7 band allocated for broadband mobile
wireless services housed in a compact 4.5 x 4.5 mm module. It
integrates a step attenuator and output power detector. According to
Ron Michels, Senior Vice President and General Manager of Broadband
Products at ANADIGICS, "Our WiMAX power amplifiers provide high
linearity and advanced functional integration to support high
performance solutions for the world's emerging broadband wireless
systems, and superior efficiency to increase battery life for a more
satisfying mobile experience." The PA module achieves 20-percent
efficiency from a +3.3-VDC supply with EVM of 2.5 percent with 16QAM
signals and +23.5-dBm output power.

Mobile WiMAX Forum PlugFest Explores Interoperability

The Second public Mobile WiMAX Forum PlugFest convened this week in
Malaga, Spain, with 35 WiMAX test equipment and product manufacturers
gathering to investigate the interoperability of their devices. Hosted
by AT4 Wireless Labs, the PlugFest attracted chipset and system
developers, including Accton Technology Corp., Adaptix, Airspan
Networks, Alcatel-Lucent, Alvarion, Aperto Networks, Beceem, GCT
Semiconductor, Huawei Technologies, Intel, LG Electronics, Motorola,
Navini, Nokia, PicoChip, POSDATA, Redline Communications, Redpine
Signals, Runcom Technologies Ltd., Samsung, SEQUANS Communications,
SOMA Networks, Telsima, Wavesat Wireless Inc., and ZTE Corp. Test
equipment suppliers included Aeroflex, Agilent, Anritsu, Rohde &
Schwarz, and Tektronix. According to WiMAX Forum President and
Chairman Ron Resnick, "The fact we have 35 companies participating in
this week's PlugFest underscores the significant interest and strong
momentum leading up to mobile WiMAX Forum Certification in mid 2007."

G. T. Microwave Hatches Up 100-W Phase Shifter

Model P6D-38N-0CC is a digital phase shifter capable of handling 100-W
CW power from 700 to 1400 MHz. It provides full 360-deg. phase control
over that frequency range, shifting in 5.63-deg. steps with 6-b TTL
digital control. The phase error as a function of frequency is less
than 20 deg. over the full frequency range while the amplitude balance
is better than 1 dB full range. The switching speed to change phase
states is an impressive 3 microseconds. The phase shifter, which
measures 5 x 2 x 0.56 inches, requires power supplies of +5 VDC and
600 mA and -9.6 VDC and 100 mA. Proper heat sinking must be applied at
a 100-W CW power level.

SMA Adapter Helps Protect Connectors

Delta Electronics Manufacturing Corp. has introduced a "Connector
Saver" adapter to prevent damage to SMA connectors on components and
cable assemblies for testing. The adapter features an SMA jack on one
end and an SMA plug modified for "Slide-on" mating on the other end.
When the jack end is fitted to an SMA plug on a cable assembly under
test, the slide-on interface saves time when connecting the assembly
to an analyzer's test port. Conversely, when testing devices fitted
with SMA jack inputs or outputs, the adapter allows the test cable to
be mated to the device with a straight push, saving the time need to
thread and torque a standard SMA plug. The adapter requires 10 lbs
maximum engagement force and 6 ounces minimum disengagement force. The
adapter exhibits maximum VSWR of 1.03:1 from DC to 18 GHz.
