SX1223 - 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.

Key Features

  • RF output power: up to +10 dBm Low power consumption: TX = 25.8 mA @ 10 dBm (typical) Supply voltage down to 2.0 V Data rate from 1.2 to 153.6 kbit/s On-chip frequency synthesizer Continuous phase 2-level FSK modulation Very small RoHS green package (TQFN24, 4mm x 4mm).
