What happens when hundreds of world-renowned engineers push the limits of RF power? More than 50 years of innovation including breakthroughs in LDMOS, GaAs, GaN and low-cost, over-molded plastic packaging. We test, validate and integrate until we exceed the highest performance standards. So your RF designs take off.
As Bluetooth wireless technology heads for its "third generation," it is a sign of the near-
insatiable global appetite for wireless services and communications. In densely populated areas,
the cellular telephone has become the lifeline for many, the main means of contacting another
party or of achieving reliable communications with a customer or business associate. As cellular
telephones head for their "fourth generation," carriers prepare to embrace additional wireless
technologies, such as WiMAX, in order to provide such advanced services and high-speed mobile
Internet access and streaming video functionality.
Bluetooth has long appeared as one of those wireless technologies "looking for a home." It has
always been designed as a short-range wireless technology, but never found its niche in
merchandising the way that radio-frequency identification (RFID) technology did. Yet, Bluetooth
is still with us, and becoming a more integral part of automotive electronics according to a new
report from IMS Research. Bluetooth has survived severe pricing pressures early in its history to
emerge as one of the more significant (and versatile) short-range wireless technologies.
If there is any one reason for this, it is the modern craving for convenience as a function of
technology. The Bluetooth cellular-phone headset, for example is both a convenience and a legal
requirement in many areas for automotive driving and cellular-phone use. Bluetooth was also
widely adopted in laptop computers and peripheral devices as a convenience. In general, wireless
technology is a convenience, a way to eliminate wires and simplify connections. For that reason,
even the most "questionable" of wireless technologies will find an application, somewhere.

Bluetooth is by now a well-established adjunct technology for cellular-telephone headsets. It is
also used in portable navigation devices, and has tremendous potential in emerging automotive
applications. Much of the success of the latest (Version 3) generation of Bluetooth products in the
automotive environment will depend on how well other wireless technologies, such as WiMAX,
wireless local area networks (WLANs), and ultrawideband (UWB) approaches fare in the
marketplace. The potential for Bluetooth technology in automotive markets will be closely
examined in a new report from IMS Research, "The Worldwide Market for Bluetooth in
Automotive Applications." For more information on the report, contact Filomena Berardi, IMS

WiMAX power amplifiers (PAs) from ANADIGICS have been specified by Beceem
Communications (www.beceem.com) for their latest model BCS200 chipset reference designs. The reference designs
support all features of the Mobile WiMAX Wave 2 profile. The ANADIGICS models
AWM6423 and AWM6432 WiMAX PA modules integrate step attenuators and output-power
detectors along with the InGaP amplifier circuitry and support error-vector-magnitude (EVM)
performance of 4 percent for 16-state quadrature-amplitude-modulation (16QAM) signals or 2.5
percent for 64QAM signals. According to Ron Michels, Senior Vice-President and General
Manager of Broadband Products at ANADIGICS, "Beceem is making the first step into 4G for
WiMAX products, and we are delighted to be a part of the BCS200 chipset reference designs."
