ISM band RF transceiver from ADI supports Zigbee and such protocols

Analog Devices has made available a RF transceiver chip targeting short-range wireless systems in the global 2.4 GHz ISM (industrial, science and medical) band. The ADF7242 featuring a communication processor supports the IEEE802.15.4 standard. This chip is suggested for implementing solutions based upon protocols such as Zigbee IPv6/6LowWPAN, ISA100.11a and Wireless HART. This device offers the flexibility to implement proprietary FSK-based protocols with data rates of up to 2 Mbps. ADI says ADF7242 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.

"With the global growth in smart grid wireless meters and infrastructure and the proliferation of cost-effective short range wireless-based systems, 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."

The immediately available ADF7242 is packed in a 5 mm x 5 mm 32-pin LFCSP package and is priced at $2.82 per unit in 1,000-unit quantities.
