GENERAL DESCRIPTION

The SX1240 is an ultra-low-cost, fully integrated FSK or OOK compatible transmitter suitable for operation in the 418, 434 and 868 MHz licence free ISM bands.

For applications where economy is paramount, the SX1240 may be used without the requirement for configuration via an MCU. The transmitter is configured for default operation at a frequency of 433.92 MHz or 868.3 MHz. However, in conjunction with a microcontroller the communication link parameters may be re-configured. Including, output power, modulation format and operating channel.

The SX1240 offers integrated radio performance with cost efficiency and is suited for worldwide operations in particular Europe (ETSI EN 300-220-1), North America (FCC part 15.231).
