GENERAL DESCRIPTION

The XE1202A TrueRF™ is a single chip transceiver operating in the 433, 868 and 915 MHz license free ISM (Industry Scientific and Medical) frequency bands. Its highly integrated architecture allows for minimum external components while maintaining design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The XE1202A TrueRF™ offers a wide range of channel bandwidths, without the need to modify the number or parameters of the external components. The XE1202A TrueRF™ is optimized for low power consumption whilst offering high RF output power and channelized operation suitable for both the European (ETSI-300-220) and the North American (FCC part 15) regulatory standards.
