The RFM69HW is a low-range, long-range, ultra-integrated RF RF transmitter-receiver capable of operating over a wide range of frequencies, including the Industry Scientific and Medical (ISM) frequency bands of 433, 868 and 915 MHz. Its highly integrated architecture allows for minimal external components while maintaining maximum design flexibility.
All major RF communication parameters are programmable and most of them can be dynamically defined. The RFM69HW offers the unique advantage of programmable narrow-band and broadband-band modes without the need to modify external components.
The RFM69HW is optimized for low energy consumption while providing high RF output power and channeled operation. TrueRF technology ™ reduces the number of external components (removal of the SAW filter) at a lower cost, while meeting ETSI and FCC regulations.
