Is this the one you're referring to? http://www.atmel.com/Images/zigbit_2.jpg
Does this particular design utilize the antenna diversity feature described
starting on page 89 of the rfa1 datasheet?
If so, it's curious to me that the Zigbit design would have two antennas so
close together, and use what I assume are identical chip antennas. Would
having identical antennas that close together--even in an antenna diversity
setup--give that much better overall performance?
