RF Transceiver Overview

The device contains a 2.4 GHz RF transceiver with a

Baseband/MAC block. The RF transceiver can be con-

trolled by the MCU for low data rate applications such as

consumer electronics, PC peripherals, toys, industrial

automations, etc. For medium data rate applications like

wireless voice and image transmission, the RF trans-

ceiver provides 1M bps turbo mode.
