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 narrow-band_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
