Low-power sub-GHz transceiver simplifies industrial wireless links

June 26, 2014 // By Graham Prophet
Analog Devices has announced a low-power radio transceiver featuring a set of configuration profiles that allow rapid radio performance optimisation, reducing system development time and shortening time-to-market.

The ADF7024 transceiver is suitable for a wide range of industrial applications, including security and building automation. The short range transceiver is designed for use in the 433-MHz, 868-MHz, or 915-MHz ISM frequency bands, and is suitable for operation under European ETSI EN300-220 and North American FCC Part 15 regulations. ADI also introduced today ADRadioNet, ( www.analog.com/ADRadioNet) a wireless protocol stack for low-power networks, and the EVAL-ADF7024MB4Z evaluation and development platform for use with the ADF7024 transceiver.

The AD7024 transceiver, $1.59 (1000) in 5 x 5-mm, 32-pin LFCSP features:

· Smart wake modes and fast mode transitions for low power consumption

· Ultra-low-power sleep modes for longer battery life

· Programmable output power up to +13.5 dBm in 0.5 dB steps

· Receiver sensitivity -111 dBm at 9.6 kbps

· Blocking: 76 dB at 10 MHz offset

ADRadioNet wireless protocol stack features;

· Self-healing, multi-hop wireless network

· Royalty-free when used with ADI transceivers

· Stateless routing; allows instantaneous recovery power up

· Network robustness through the use of channel diversity

The EVAL-ADF7024MB4Z evaluation and development platform ($200) features:

· Easy to use evaluation GUI

· Selectable radio profiles

· Example microcontroller code
