Because of 1.2K baud rate CC1101 peripheral circuit parameters relatively high precision, to improve the effective communication distance, especially developed to change the module, this module is a unit from the domestic R & D special customization, has volume use.

CC1101 CC1100 major improvement in part 
to improve the spurious response; 
tighter phase noise better improvement adjacent channel power (ACP) performance; 
higher saturation level inputs; 
higher performance power output 
continuous frequency band extension

CC1100: 400-464 MHz and 800-928 MHz 
CC1101: 387-464 MHz and 779-928 MHz

1. 1% of the peripheral circuit device uses high-precision external parameters,

2. 1.2K baud designed specifically for low-speed, improve communication distance 1101

3. Smaller and more stable than ordinary CC1100 module, and 1.2K baud rate, long distance 50-100 meters
