Analog Devices offers WSN transceiver

LONDON — Analog Devices Inc. has announced today the availability of an RF transceiver targeting short-range wireless systems in the 2.4-GHz ISM 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.

Applications include smart meters, smart grids, wireless sensor networks, building automation, industrial wireless control, wireless remote controls, consumer electronics and healthcare, Analog Devices said.

The ADF7242 features a communications processor and 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 blocking resistance that allows the device to operate in the crowded 2.4-GHz band, where interfering signals are greater than 30 times stronger. Furthermore, the high sensitivity and low power consumption more than double the operating range of the radio while increasing the battery life.

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