CC1070 is a true single-chip UHF transmitter designed for very low power and very low voltage wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 402, 424, 426, 429, 433, 447, 449, 469, 868 and 915 MHz, but can easily be programmed for multi-channel operation at other frequencies in the 402 - 470 and 804 - 940 MHz range.

The CC1070 is especially suited for narrowband systems with channel spacings of 12.5 or 25 kHz complying with ARIB STD T-67 and EN 300 220.

The CC1070 main operating parameters can be programmed via a serial bus, thus making CC1070 a very flexible and easy to use transmitter. In a typical application CC1070 will be used together with a microcontroller and a few external passive components.
