Description  
The CC1120 is  
a fully integrated single-chip radio  
transceiver designed for high performance at very low  
power and low voltage operation in cost effective wireless  
systems. All filters are integrated, removing the need for  
costly external SAW and IF filters. The device is mainly  
intended for the ISM (Industrial, Scientific and Medical)  
and SRD (Short Range Device) frequency bands at 164-  
192 MHz, 274-320 MHz, 410-480 MHz and 820-960 MHz.

The CC1120 provides extensive hardware support for  
packet handling, data buffering, burst transmissions, clear  
channel assessment, link quality indication and Wake-On-  
Radio. The CC1120 main operating parameters can be  
controlled via an SPI interface. In a typical system, the  
CC1120 will be used together with a microcontroller and  
only few external passive components.
