ADI delivers RF transceiver for short-range wireless systems

analogdeviceslogoNorwood, Mass. — Analog Devices, Inc. (ADI) has unveiled a RF transceiver that targets 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 on protocols such as Zigbee IPv6/6LowWPAN, ISA100.11a and Wireless HART, as well as proprietary FSK-based protocols with data rates of up to 2 Mbits/s.

ADI said the ADF7242 short range transceiver offers best-in-class blocking resistance to increase signal quality and range and to extend battery life. Applications include smart meters/smart grid, wireless sensor networks, building automation, industrial wireless control, wireless remote controls, consumer electronics and healthcare.

The fully-integrated, low-power ADF7242 features a communications processor to reduce system complexity and to enable engineers to use less powerful and more power efficient controllers, said ADI. Other features include dual-mode IEEE802.15.4 and GFSK/FSK operations, allowing the device to support the IEEE 802.15.4 based protocol standards at 250 Kbits/s as well as proprietary protocols up to 2 Mbits/s 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, said ADI. The high sensitivity and low-power consumption of the device is said to more than double the operating range of the radio while increasing the battery life.

The ADF7242 works with a variety of ADI products, including the Blackfin processor.
