Overview
The CC1101RGPT is a low-cost sub-1 GHz transceiver designed for very low-power wireless applications. It is manufactured by Texas Instruments and 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. However, it 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.
