ANALOG DEVICES INTRODUCES HIGHLY INTEGRATED, LOW-POWER RF TRANSCEIVER FOR SHORT-RANGE WIRELESS SYSTEMS IN INDUSTRIAL, SCIENCE AND MEDICAL APPLICATIONS

ADI's ADF7241 RF transceiver operates in the global 2.4 GHz ISM-band frequency range; supports 250 Kbps IEEE 802.15.4 PHY protocol on a single chip.

Norwood, MA (02/23/2011) - Analog Devices, Inc. (ADI), a global leader in semiconductors for high-performance signal processing applications and RF ICs (radio frequency integrated circuits), today introduced a highly integrated, low-power RF transceiver for operation in the global 2.4 GHz ISM (industrial, scientific and medical) frequency band. As the latest addition to ADI's extensive RF IC product portfolio, the ADF7241 RF transceiver is designed with emphasis on flexibility, ease-of-use characteristics, and low power consumption. The highly integrated ADF7241 RF transceiver enables support of the standard IEEE 802.15.4 PHY protocol at 250 kbps on a single chip. The transceiver's low-power consumption of 19mA in receive mode and 21.5 mA in transmit mode makes it effective for battery-powered systems, such as wireless sensor networks, automatic meter reading, industrial wireless control, wireless audio and video, consumer electronics, and ZigBee® applications.

The receive path of the ADF7241 RF transceiver is based on a zero-IF architecture enabling best-in-class blocking and high selectivity performance, while the transmit path is based on a closed loop VCO (voltage controlled oscillator) modulation scheme, which provides a high modulation quality. It also features a flexible port RF-interface with support for switched antenna diversity. In order to optimize the system power consumption, the ADF7241 RF transceiver incorporates a robust, very low-power, custom 8-bit processor that supports a number of RF functions, including radio control and packet management. The integrated 8-bit processor is firmware that can be programmed to execute firmware modules or system upgrade patches from internal RAM memory, which provides the flexibility to respond to protocol standard evolution and maintain system robustness.

The ADF7241 RF transceiver is equipped with a SPI (serial port interface) for high throughput efficiency as well as a bi-directional SPORT (serial port). The transceiver can be easily designed into system designs with ADI's ADSP-21xx, SHARC®, TigerSHARC® , and Blackfin® Processors.

ADF7241 ISM-band RF Transceiver Key Features:

  • Low power consumption: 19 mA in receive mode; 21.5 mA in transmit mode; 1.7 µA, 32 kHz crystal oscillator wake-up mode
  • High sensitivity: -95 dBm at 250 kbps
  • Programmable output power: -20 dBm to +4.8 dBm in 2 dB steps
  • Integrated voltage regulators: 1.8 V to 3.6 V input voltage range
  • Complies with a number of industry standards, including EN300 440 Class 2, EN300 328, FCC CFR47 Part 15, ARIB STD-T66
