Overview
The CC1101RGPR is a low-cost sub-1 GHz wireless transceiver designed by Texas Instruments for very low-power wireless applications. It is primarily intended for use in the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can be programmed to operate at other frequencies within the 300-348 MHz, 387-464 MHz, and 779-928 MHz bands. The device integrates a highly configurable baseband modem that supports various modulation formats and has a configurable data rate up to 600 kbps. It is suited for systems targeting compliance with EN 300 220 (Europe) and FCC CFR Part 15 (US), as well as the Wireless MBUS standard EN 13757-4:2005.
