Overview
The CC1125RHBT is a high-performance, single-chip radio transceiver designed by Texas Instruments. It is optimized for low-power and low-voltage operation in cost-effective wireless systems. The device integrates all necessary filters, eliminating the need for external SAW and IF filters. It operates within the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands, covering ranges from 164–192 MHz, 274–320 MHz, 410–480 MHz, and 820–960 MHz. The CC1125RHBT is controlled through an SPI interface and is typically used with a microcontroller and a few external passive components.
