图1CC1200内部结构图

TheThe CC1200 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 164–190 MHz,410–475 MHz, and 820–950 MHz.

The CC1200 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 CC1200 device can be controlled through an SPI interface. In a typical system, the CC1200 device will be used with a microcontroller and only a few external passive components.
