3 Overview
The radio extender board is assembled with an Atmel AT86RF232 radio transceiver
[1] and two
ceramic antennas, and demonstrates the unrivaled hardware-based
antenna diversity feature, which significantly improves radio link robustness in harsh
environments.
The radio extender board was designed to interface to the Atmel microcontroller
development or evolution platforms. The microcontroller platform in combination with
the REB provides an ideal way to:
• Evaluate the outstanding radio transceiver performance, such as the excellent
receiver sensitivity achieved at ultra-low current consumption
• Test the radio transceiver’s comprehensive hardware support of the IEEE
802.15.4™ standard
• Test the radio transceiver’s enhanced feature set, which includes antenna
diversity, AES, high data rate modes and other functions
