SX1240 - Low Cost Integrated Transmitter IC
434 MHz and 868 MHz Band RF Transmitter
DATASHEET
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).
