The RF31 offers advanced radio features including continuous frequency coverage from 240–960 MHzThe RF31‘s high level of
integration offers reduced BOM cost while simplifying the overall system design. The extremely low receive sensitivity (–118
dBm) ensures extended range and improved link performance. Built-in antenna diversity and support for frequency hopping can
be used to further extend range and enhance performance.
Additional system features such as an automatic wake-up timer, low battery detector, 64 byte RX FIFO, automatic packet
handling, and preamble detection reduce overall current consumption and allow the use of lower-cost system MCUs. An
integrated temperature sensor, general purpose ADC, power-on-reset (POR), and GPIOs further reduce overall system cost
and size.
The RF31‘s digital receive architecture features a high-performance ADC and DSP based modem which performs
demodulation, filtering, and packet handling for increased flexibility and performance. This digital architecture simplifies system
design while allowing for the use of lower-end MCUs.
