XE1203F
433 MHz / 868 MHz / 915 MHz
Low-Power, Integrated UHF Transceiver
GENERAL DESCRIPTION
The XE1203F 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
flexibility. All major RF communication parameters
are programmable and most of them can be
dynamically set. The XE1203F offers the excellent
advantage of high data rate communication at rates
of up to 152.3 kbit/s, without the need to modify the
number or parameters of the external components.
The
consumption while offering high RF output power and
exceptional receiver sensitivity. The device is suitable
for applications which have to satisfy either the
European (ETSI-300-220) or 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.
