SX1223
SX1223
425 – 475 MHz / 850 – 950 MHz
Integrated UHF Transmitter
GENERAL DESCRIPTION
KEY PRODUCT FEATURES
The SX1223 is a single chip transmitter operating in
UHF frequency bands including the 434, 869 and 915
MHz license-free ISM (Industrial Scientific and
Medical) 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 set dynamically. The SX1223
offers the advantage of high data rate communication
at rates of up to 153.6 kbit/s. The SX1223 is
optimized for low cost applications while offering high
RF output power. The device is suitable for
