1.3 Description
The CC1175 device is a fully integrated single-chip radio transmitter 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 164–192 MHz,
274–320 MHz, 410–480 MHz, and 820–960 MHz.
The CC1175 device provides extensive hardware support for packet handling, data buffering, and burst
transmissions. The main operating parameters of the CC1175 device can be controlled through an SPI
interface. In a typical system, the CC1175 device will be used with a microcontroller and only a few
external passive components.
