The Texas Instruments CC1101RGPR is a sub-1 GHz RF transceiver supporting ASK, OOK, FSK, GFSK, and MSK modulation, with one transmitter and one receiver, in a 20-pin VQFN with exposed pad measuring 4 mm x 4 mm. It covers a 915 MHz to 928 MHz range in this configuration, reaches -116 d Bm sensitivity, supports data rates to 600 kbps, and connects to a host through SPI. The CC1101RGPR runs from 1.8 V to 3.6 V, drawing 17.1 mA receiving and 34.2 mA transmitting, and is rated -40°C to 85°C on 3, 000-piece tape and reel.

Sub-1 GHz radios are used where range and building penetration matter more than bandwidth, because the lower carrier frequency propagates further and through walls better than 2.4 GHz for the same transmit power. The 915 MHz band is the North American license-free ISM allocation, so this device targets proprietary and standards-based links in that region. Typical applications are wireless sensor networks, utility and sub-metering, alarm and security systems, remote keyless and garage controls, industrial telemetry and SCADA links, and home automation. The multi-modulation support and SPI interface let a designer pair it with almost any microcontroller and tune the trade-off between range, data rate, and current draw; buyers are IoT, metering, security, and industrial OEMs.
