DWM-VT-CC1120 433MHz /868MHz /915MHz Narrow-Band TI CC1120 wireless Transceiver module is based TI Chipcon RF Transceiver CC1120，it’s a small size and ultra low power UHF wireless module.CC1120 is fully integrated single-chip radio transceiver designed for high performance at very low power and low voltage operation in cost effective wireless systems. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 164-192 MHz, 410-480 MHz and 820-960 MHz. The MAX RF output power can be set as high as +16dBm, with data rate as high as 200Kbps. The module integrated many RF functions thus you can use it conveniently and reducing your development time.

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.
