The SX1239 from Semtech is a highly integrated RF receiver capable of operation over a wide frequency range up to 1GHz, including the 433MHz, 868MHz and 915MHz licence- free ISM bands.
Its highly integrated architecture allows designers to implement a complete receiver circuit with minimal external components while maintaining design flexibility. All the main RF communication parameters are programmable, and most of them can be set dynamically.
Featuring Semtech’s TrueRFTM technology, the SX1239 saves cost by eliminating the need for an external Surface Acoustic Wave (SAW) filter, while still satisfying the requirements of ETSI and FCC regulations.
