1.3 Description

The CC1120 device 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, thus

removing the need for costly external SAW and IF filters. The device is mainly intended for Industrial,

Scientific, and Medical (ISM) applications and Short Range Device (SRD) frequency bands at

164 to 192 MHz, 274 to 320 MHz, 410 to 480 MHz, and 820 to 960 MHz.

The CC1120 device provides extensive hardware support for packet handling, data buffering, burst

transmissions, clear channel assessment, link quality indication, and wake-on-radio. The main operating

parameters of the CC1120 device can be controlled through an SPI interface. In a typical system, the

CC1120 device is used with a microcontroller and only a few external passive components.
