425 – 475 MHz / 850 – 950 MHz

Integrated UHF Transmitter

GENERAL DESCRIPTION

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

applications which have to satisfy either the European

(ETSI-300-220) or the North American (FCC part 15)

regulatory standards.

APPLICATIONS

• Automated Meter Reading (AMR)

• Home Automation and Access Control
