The CC1150 is a true single-chip UHF transmitter designed for very low power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315-, 433-, 868-, and 915-MHz, but can easily be programmed for operation at other frequencies in the 300 to 348 MHz, 400 to 464 MHz and 800 to 928 MHz bands.
The RF transmitter is integrated with a highly configurable baseband modulator. The modulator supports various modulation formats and has a configurable data rate up to 500 kBaud. The CC1150 device provides extensive hardware support for packet handling, data buffering and burst transmissions.
The main operating parameters and the 64-byte transmit FIFO of CC1150 can be controlled via an SPI interface. In a typical system, the CC1150 device will be used together with a microcontroller and a few additional passive components.
CC1150 is part of the SmartRF™ technology platform based on 0.18-μm CMOS technology from Texas Instruments.
