Overview

The CC1120RHBT is a high-performance, fully integrated single-chip radio transceiver designed for operation in the sub-1GHz ISM and SRD frequency bands. It features exceptional sensitivity of -127dBm and high selectivity, making it ideal for narrowband systems and long-range wireless communication applications.

Why Choose This Part

The CC1120RHBT offers a superior link budget and advanced digital signal processing through WaveMatch for improved sync detect performance. It supports a wide range of modulation formats including 4GFSK and MSK, while maintaining an ultra-low sleep current of 0.5uA for extended battery life.

Applications

Narrowband Wireless Systems
Optimized for 12.5kHz and 25kHz channel spacing systems requiring high adjacent channel rejection.
Smart Metering
Ideal for AMR (Automatic Meter Reading) and AMI (Advanced Metering Infrastructure) in the 868MHz and 915MHz bands.
Industrial Monitoring
Provides reliable long-range data links for industrial sensors and wireless control networks.
Home and Building Automation
Supports smart lighting, security systems, and environmental controls with low power consumption.
