Overview
The CC1120RHBT is a high-performance, single-chip RF transceiver designed by Texas Instruments for narrowband wireless systems. This device is optimized for low-power and low-voltage operation, making it suitable for a wide range of industrial, scientific, and medical (ISM) applications and Short Range Device (SRD) frequency bands. The CC1120RHBT integrates all necessary filters, eliminating the need for external SAW and IF filters, and supports extensive hardware functions for packet handling, data buffering, and clear channel assessment.
