Choosing When To Build In China

Credit is due to companies like RF Micro Devices (see story below)
for the amazing achievement of so many amplifier modules assembled
in China. To reach 100 million units implies not only healthy sales,
but the foresight to have established a facility in Beijing and to
train people there to properly handle RF integrated circuits and
circuit elements used in the assembly of modules. For
price-sensitive markets involving large-volume manufacturing, the
competitive pricing of assembly facilities in China, Indonesia, and
other Far East locations have priced many Mexican operations out of
the market, not to mention assembly in the United States or Europe.

Of course, assembly in the Far East only goes so far. During a visit
for another publication, Penton's Military Electronics ( available at
http://news.mwrf.com/t?ctl=2DD5D:49027F ), a local designer
and manufacturer of powerline filters for military and commercial
applications, Zero Surge ( http://news.mwrf.com/t?ctl=2DD57:49027F )
and Chief Engineer Rudy Harford noted that their products were
manufactured entirely in the United States and built to military
standards. In examining the workmanship, the care and precision of
the assembly was obvious: these were surge removal filters that
were guaranteed for 10 years and would probably last much longer.

The assembly quality from the Far East has improved dramatically
over the last few years, but has a long way to reach products such
as the Zero Surge filters. For consumer electronics, which tend to
be "disposable" products, the Far East workmanship is good enough.
But for critical products, look elsewhere for your assembly

Sonnet Remembers Maxwell At MTT-S

Next Tuesday, June 13th, marks the 175th anniversary of the birth of
James Clerk Maxwell, perhaps best known for the equations that are
the basis for electromagnetic (EM) theory. In celebration of the
event, and recognition of what Maxwell's accomplishments have meant
for the microwave industry, Sonnet Software is throwing a party at
the annual Microwave Theory & Techniques Symposium (MTT-S) in San
Francisco. Scheduled for 7 PM at the San Francisco Marriott Hotel,
the event is co-hosted by Computer Systems Technology (CST) and the
2006 International Microwave Symposium (IMS) Committee. It will
feature free refreshments and a presentation by Dr. James Rautio,
president and founder of Sonnet Software and MTT-S Distinguished
Microwave Lecturer, on the life of James Clerk Maxwell. What
profound event affected Maxwell when he was just eight years old?
And what does he have to do with the rings of Saturn? For answers,
don't miss Jim Rautio's entertaining and informative talk, as well
as free drinks and cake.

Elcom Extends Range of SIGINT Receivers

Suitable for use with a wide range of receivers, notably for signal
intelligence (SIGINT) applications, the ELFE frequency extender from
Elcom Technologies allows an 18-GHz receiver to cover frequency
bands from 18 to 40 GHz. By adding these bands, it extends a
broadband receiver's standard operating range above and beyond the
traditional 0.5 to 18.0 GHz. The ELFE offers one input port for
signals from 0.5 to 18.0 GHz, which can be passed cleanly through
the ELFE and connected to a receiver. A second RF input port accepts
signals from 18 to 40 GHz, which are downconverted to the
2-to-18-GHz range and then connected to the receiver or tuner.

AR Addresses Changes In EMC Testing

Testing for radiated electromagnetic (EM) field immunity testing has
long been performed according to the IEC 61000-4-3 standard in order
to satisfy many European Union requirements for the CE mark. But
Edition 3.0 of that standard has introduced many changes, including
a new harmonic distortion requirement, new linearity check, an
extended frequency range, and new test table material requirements.
These modifications have some electromagnetic compatibility (EMC)
labs pondering how to meet the new requirements, what type of
equipment to add. Fortunately, AR Worldwide has addressed the
changes to the standard and how to meet the new requirements in new
literature, Application Note #41. It offers a number of helpful tips
that labs should try before purchasing new amplifiers for an EMC
test lab. Copies are free for download from the company's website.

Conexant Expands WLAN Connectivity For Portables

Conexant Systems, Inc. has added to its low-power Wi-Fi wireless
local area network (WLAN) product line with the introduction of the
model CX53121 radio chip. The third-generation IEEE 802.11b/g device
integrates a WLAN transceiver, power management, and supporting
components into a single 68-square-millimeter chip. The CX53121
features a high-performance transceiver that delivers transmit power
as high as +19.5 dBm and sensitivity below -90 dBm. It includes
secure digital input-output (SDIO) interface, serial peripheral
interface (SPI), and support for coexistence with Bluetooth devices.
It is targeted at battery-powered handheld products with embedded
wireless networking capabilities such as cell phones, smartphones,
voice over Internet protocol (VoIP) handsets, cameras, MP3 players,
gaming consoles and global positioning system (GPS) devices.

RFMD Assembles 100 Millionth Module in China

China has been good to RF Micro Devices (RFMD). The company
yesterday announced that it had assembled its 100 millionth RF
module in its Beijing, China assembly facility. The company
attributes the achievement to continued strong sales of its cellular
power amplifier (PA) modules worldwide. According to company
president and CEO Bob Bruggeworth, "we are committed to increasing
our manufacturing capabilities in Asia as the region continues to
evolve as the handset industry's manufacturing center." The firm's
amplifiers can be found in about half of the world's cellular
telephones. Due to increasing demand, RFMD is increasing its
assembly capacity in Beijing by about 100 percent.
