High performance low power Sub-1 GHz wireless transceiver

The CC1121 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 the ISM (Industrial, Scientific, and Medical) and SRD

(Short Range Device) frequency bands at 274–320 MHz, 410–480 MHz, and 820–960

MHz.

The CC1121 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 CC1121 device can be controlled through an SPI interface. In a

typical system, the CC1121 device will be used with a microcontroller and only a few

external passive components.
