Low-Power Sub-1-GHz Fractional-N UHF Device Family for Automotive

The CC11x1-Q1 device family is designed for very low-power wireless applications. The circuits are mainly intended for the Industrial, Scientific and Medical (ISM) and Short Range Device (SRD) frequency bands at 315 MHz, 433 MHz, 868 MHz, and 915 MHz, but can easily be programmed for operation at other frequencies in the 310-MHz to 348-MHz, 387-MHz to 464-MHz, and 779-MHz to 928-MHz bands.
