Overview
The CC1050, produced by Texas Instruments, is a true single-chip UHF RF transmitter designed for very low power and very low voltage wireless applications. It operates within the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can be programmed for other frequencies in the 300-1000 MHz range. The device is based on Chipcon’s SmartRF® technology in 0.35 µm CMOS and is highly flexible and easy to use, requiring very few external components.
