Product Description
CC1021 is a true single-chip UHF transceiver 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 433, 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.
