XE1205
180 MHz – 1GHz
Low-Power, High Link Budget Integrated UHF Transceiver
GENERAL DESCRIPTION
The XE1205 is an integrated transceiver operating in
the 433, 868 and 915 MHz license-free ISM (Industrial,
Scientific and Medical) frequency bands; it can also
address other frequency bands in the 180-1000 MHz
range. 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 XE1205 offers the unique
advantage of narrow-band and wide-band
communication, this without the need to modify the
number or parameters of the external components.
The XE1205 is optimized for low power consumption
while offering high RF output power and channelized
operation suited for both the European (ETSI EN 300-
220-1) and the North American (FCC part 15)
regulatory standards. TrueRF™ technology enables a
low-cost external component count (elimination of the
SAW filter) whilst still satisfying ETSI and FCC
regulations.
