Note:
1.The module transmission data rate will affect Transmission distance ,the higher the data rate , the closer the distance, and the lower the receiving sensitivity.
2.The supply voltage to the module will affect TX power, in the operating supply voltage range, the lower the voltage, the lower the TX power.
3.The module central frequency will change as the operating temperature change, use it under suggest temperature, the module can work well.
4.The antenna will strongly affect the communication distance, please select matched antenna and connect it correctly.
5.The module mount will affect the communication distance.

Circuit Interface
Note:
The pin sequence above are not the actual pin sequence refer pin description. SPI, I/O interface should connect with the MCU’s I/O pin in order to archive your functions. The circuit must be take ESD protect to prevent damage module. Good RF performance determines on the module position, ground and antenna fixing. Any question about the module please contact with the FAE engineer.
Configuration Registers
The configuration of CC1120 can be done with software SmartRF Studio7. Complete descriptions of the registers are given in the CC1120 datasheet. We can provide evaluation board and demo code to the customer to develop and evaluate the module’s capability.
