Description
VT-CC1121-433M is based on RF Transceiver CC1121 of TI Chipcon ， it’s a small size and ultra low power UHF
wireless module. CC1121 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 +15dBm, 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
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.
