XE1202A TrueRF™

433 MHz / 868 MHz / 915 MHz

Low-Power, Integrated UHF Transceiver

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.

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.
