GENERAL DESCRIPTION
The SX1208 is a highly integrated RF transceiver capable of
operation from 290MHz to 510MHz, including the 315 and
434 MHz license-free ISM (Industry Scientific and Medical)
frequency bands. Its highly integrated architecture allows for
a minimum of external components whilst maintaining
maximum design flexibility. All major RF communication
parameters are programmable and most of them can be
dynamically set. The SX1208 offers the unique advantage
of programmable narrow-band and wide-band
communication modes without the need to modify external
components. The SX1208 is optimized for low power
consumption while offering high RF output power and
channelized operation. TrueRF™ technology enables a low-
cost external component count (elimination of the SAW
filter) whilst still satisfying ETSI and FCC regulations.
