SX1240 - Low Cost Integrated Transmitter IC

434 MHz and 868 MHz Band RF Transmitter

SX1240, Rev 1, Oct 2010

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).
