Analog Devices Press Release - March 8, 2010

Analog Devices Introduces High Performance, Radio Frequency Circuit for Short-range Wireless Systems in Industrial, Science and Medical Applications

- New 2.4 GHz ISM Band short range RF transceiver supports either 250 Kbps in IEEE802.15.4 mode
  or up to 2Mbps in FSK mode and offers the industry’s best blocking resistance.

Visit Analog DevicesMarch 8, 2009 -- NORWOOD, Mass.-- (BUSINESS WIRE)-- Analog Devices, Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal-processing applications and leading provider of RF ICs (radio frequency integrated circuits), announced today the availability of an RF transceiver targeting short-range wireless systems in the global 2.4 GHz ISM (industrial, science and medical) band. The transceiver supports the IEEE802.15.4 standard and may be used to implement solutions based upon protocols such as ZigBee® IPv6/6LowWPAN, ISA100.11a and Wireless HART, as well as offering the flexibility to implement proprietary FSK-based protocols with data rates of up to 2 Mbps. ADI’s new ADF7242 short range transceiver offers best-in-class blocking resistance to increase the effective signal quality and range as well as prolong battery life. Applications include smart meters/smart grid; wireless sensor networks, building automation, industrial wireless control, wireless remote controls, consumer electronics and healthcare.

           range
  • See data sheet for additional Features
“With the global growth in smart grid wireless meters and infrastructure and the proliferation of cost-effective short range wireless-based systems, such as ZigBee, there is an increasing demand for robust performance, low power consumption, flexibility and ease-of-use all combined within a single radio chip,” said Peter Real, vice president, linear and RF group, Analog Devices, Inc. “ADI’s ADF7242 combines our high performance RF, analog, signal processing and integration expertise to deliver a robust solution that addresses these needs.”

About the ADF7242 RF Transceiver

The ADF7242 is a fully integrated, low-cost, low power short range transceiver and has been designed with emphasis on flexibility, ease of use and low current consumption. The ADF7242 features a robust communications processor to reduce system complexity and enable engineers to use less powerful and more power efficient controllers. It features dual-mode IEEE802.15.4 and GFSK/FSK operations, whereby the same device is capable of supporting the IEEE 802.15.4 based protocol standards at 250 Kbps as well as proprietary protocols up to 2 Mbps using GFSK/FSK modulation schemes on a single chip. The transmit and receive paths of the ADF7242 provide industry-leading blocking resistance that allows the device to operate in the crowded 2.4 GHz band, where interfering signals are greater than 30x stronger. Furthermore, the high sensitivity and low power consumption more than double the operating range of the radio while increasing the battery life. A complete datasheet with full specifications can be viewed at www.analog.com/pr/adf7242.

Pricing, Availability and Complementary Products

The ADF7242 is available now in a 5 mm x 5 mm 32-pin LFCSP package and is priced at $2.82 per unit in 1,000-unit quantities. The ADF7242 works well with a variety of ADI products, including the Blackfin® Processor.

ADI’s RF IC Portfolio Covers Entire RF Signal Chain

Using a unique combination of design skills, system understanding and process technologies, Analog Devices offers the broadest portfolio of RF ICs covering the entire RF signal chain from industry-leading high-performance RF function blocks to highly integrated WiMAX and short-range, single chip transceiver solutions. The RF function blocks include PLL, integrated PLL/VCO and DDS synthesizers; TruPwr™ RMS power detectors and logarithmic amplifiers; X-Amp® variable gain amplifiers; power amplifiers, low noise amplifiers and other amplifiers; RF mixers and direct conversion modulator and demodulator products. These products are supported by a wide range of free design tools to ease the development of RF systems. For more information, visit http://www.analog.com/RF.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
