RF System Overview
The following circuit schematics show two possible RF configurations. The first supports dual band
(5GHz and 2.4GHz) and includes support to transmit and receive diversity. The second circuit is a
simplified version that supports single band (2.4GHz) and a single antenna (no diversity).
