ParkerVision Announces RF Power Amplifiers that Reduce Transmitter Power Consumption20 January 2005
This breakthrough in cost, size, and
performance is made possible by the company's expertise in converting
traditional analog designs into advanced digital architectures. ParkerVision's
power amplifiers incorporate a proprietary all digital circuit architecture
that replaces traditional analog circuitry.
ParkerVision's power amplifiers will significantly extend battery life in
mobile wireless RF products and help designers improve cost and size by
reducing the size of the battery. In certain applications, such as Wi-Fi,
ParkerVision's power amplifiers will enable manufacturers to provide
networking gear that delivers higher data rates at greater distances, with
significantly increased coverage and reliability, by providing greater RF
transmitted power than is currently available in the market today.
The level of power efficiency achieved by ParkerVision's proprietary
digital power amplifiers replaces the commonly used analog RF power amplifiers
used today and far surpasses the efficiency of such offerings. Alan Varghese,
Principal Analyst with ABI Research, states "today's wireless users demand
higher performance devices which place increasing demands on battery life. The
cost-saving desire for smaller batteries and the demand for increased range
will be important factors in manufacturers' design decisions moving forward."
"Our products will empower manufacturers with a new solution to create
unparalleled choices in efficiency, cost, size, and performance for their
wireless products," commented Jeffrey Parker, ParkerVision CEO. "We will
immediately begin working with manufacturers to configure the offering to
their needs and provide samples mid-year, with volumes available later in the
year. We are targeting high volume as well as fast growth applications. Our
product line, built from common low cost silicon semiconductors, will
incorporate into single chips the same ease of design that manufacturers have
come to rely upon from multi-component modules that dominate the PA market
today. ParkerVision expects to be shipping its own branded products that
incorporate our digital power amplifier chips by end of this year."
D2D Technology
Extending the science behind its patented Direct2Data(TM) (D2D(TM))
digital RF transceiver technology into power amplifiers, the new products
target product applications that are forecasted to consume nearly one and a
half billion RF power amplifiers this year and will continue to grow at up to
18% unit volumes year over year - according to a report by Allied Business
Intelligence (ABI). RF power amplifiers are a critical component of all
wireless RF devices used in digital communications. They boost the transmitted
RF signal so that it can reach its intended destination. The transmitter in
these devices is commonly the single largest power consumer oftentimes
accounting for the majority of all power used by a wireless RF product.
While traditional RF power amplifiers are built from legacy analog circuits
with inherent efficiency and performance limitations, ParkerVision's digital
RF power amplifiers benefit from the only 100% digital architecture.
ParkerVision's power amplifiers reduce total transmitter power consumption by
50% to 80%.
Parker continued, "Our expertise in high performance digital architectures
allowed us to create an ultra-efficient all digital power amplifier
technology. The excellent linearity of our proprietary technology makes it
applicable to all wireless RF digital communications, even challenging
applications such as CDMA or OFDM used in higher data rate Wi-Fi applications.
Product Applications
The initial ParkerVision digital power amplifier product lineup includes
models for:
-- CDMA2000 1x 1xRTT, 1xEVDO, and 1xEVDV
-- GSM/GPRS/EDGE
-- IMT-2000 W-CDMA for UMTS
-- Wi-Fi 802.11b/g/n wireless networking gear
-- Bluetooth enabled devices
-- Cordless and VoIP Phones
-- Multi-mode/multi-band products that combine the standards
listed above
The company's first offerings will be for applications up to 3GHz RF
frequencies. It expects later this year to announce additional models up to
6Ghz RF frequencies that will target applications for the Wi-Fi 802.11a
standard, additional cordless phone applications, and other applications.
ParkerVision has filed for patents for its unique digital power amplifier
technology. The company has 20 U.S. and 37 foreign patents issued, and 87
patents pending for its wireless technology.
About ParkerVision
ParkerVision, Inc. is headquartered in Jacksonville, Fla. with additional
facilities in Orlando, Florida. The company's new RF power amplifier products
provide chip and technology solutions to manufacturers of wireless RF
products. The company designs, develops and manufactures complete
semiconductor system solutions for wireless products based on the enabling,
patented D2D(TM) technology. D2D, which is applicable to all wireless
applications, utilizes digital radio circuitry that eliminates the negative
attributes inherent to products that use legacy analog processes. Based on the
superior performance of our D2D technology, ParkerVision guarantees that its
SignalMAX(TM) complete networking solutions will offer "full home coverage"
and eliminate "dead-zones." The company is also introducing cordless phones
under the SignalMAX brand.
