Analog Devices introduces new RF circuit for short-range wireless systems

Semiconductors manufacturer Analog Devices, Inc., and provider of RF ICs (radio frequency integrated circuits), is offering 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 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, 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.
