Milestone for RF detector production
Analog Devices has shipped its 50 millionth radio frequency detector IC for cellular handsets
Providing higher accuracy and greater dynamic range over both discrete circuits and competitors' ICs, ADI's RF detectors have steadily been gaining market share since their introduction in 2000. Addressing the most common problems affecting cell phone users - dropped calls and low battery life - ADI's family of RF detector ICs have been employed by eight out of the top ten cellphone manufacturers worldwide.
"ADI has quietly been revolutionising the RF detector function in cellular handsets over the past two years", said Robbie McAdam, Vice President, Analog Semiconductor Components, Analog Devices.
"With 50 million ICs shipped into this market, we have brought to manufacturers a technical innovation that significantly improves the experience of cell phone users worldwide.
Given our success in this area and our expertise in RF technology, we will continue to deliver best-in-class IC solutions to a market in which billions more cell phones will be sold over the next few years".
"With 410 million cellular handsets produced in 2002, this area of consumer electronics is still one of the fastest growing markets worldwide", said Stan Bruederle, Chief Analyst, wireless semiconductor Applications, Gartner Dataquest.
"Further, with the projected number of cellular handsets expected to reach 500 million-per-year by 2006, the cellular phone handset segment will be robust for years to come".
ADI's RF detector ICs provide precise control of RF power amplifiers operating in the frequency range of 0.1-2.5GHz and over a typical dynamic range of 50dB.
Complying with both GSM and CDMA standards, the company's family of RF detector ICs - which includes the AD8315 - can be used for all single and multiband phones, a convenience factor for cellphone designers.
Because these parts provide high accuracy even at low signal levels, they minimise the required power from the power amplifier - thus extending battery life.
