The 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.

“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 RF, analog, signal processing and integration expertise to deliver a robust solution that looks to address these needs.”

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. It 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.
