CC1101射频的UHF收发器解析CC1101在CC1100主要改善部分改善杂散响应；更紧密的相位噪声更好的改善邻道功率（ACP ）的性能；饱和电平输入更高；更高效能的功率输出连续频率波段的扩展，CC1100: 400-464 MHz 和800-928 MHzCC1101: 387-464 MHz 和779-928 MHz产品简介CC1100/CC1101是Chipcon（已被TI收购）推出的一款低成本单片射频的UHF收发器。
该芯片电路主要设定为在315、433、868和915MHz 的ISM（工业，科学和医学）,集成了一个软件可编程的调制解调器。
该调制解调器支持2-FSK、GFSK和MSK调制格式，数据传输率最高可达500kbps。
通过开启集成在调制解调器上的前向误差校正选项，能使性能得到提升。
CC1100/CC1101硬件支持数据包处理、数据缓冲、突发数据传输、清晰信道评估、连接质量指示和电磁波激发MCU可以通过SPI 接口与CC1100进行命令和数据交换。
CC1100/CC1101主要应用于低功耗无线应用设计。
CC1101在CC1100基础上主要进行以下改进改善杂散响应,饱和电平输入更高；连续频率波段的扩展：CC1100: 400-464 MHz和800-928 MHz；CC1101: 387-464 MHz和779-928 MHz；CC1101和CC1100二者在软件编程上完全兼容；更高效能的功率输出，能量越集中，信号传输就越远；更紧密的相位噪声更好的改善邻道功率（ACP）的性能，改善了近距离信号堵塞现象。
虽然CC1100芯片还存在，但鉴于CC1101的改进特性，我公司研制的模块已经从09年开始全部采用CC1101芯片。
为便于用户开发，我们提供配套评估套件，为产品开发保驾护航，使无线应用开发大大加速，并避免不必要的误区。
