China Direct Sale 1200Bps-200Kbps Data Rate CC1120 15Dbm Receive Rf Module


VT-CC1120-433/868M is based on RF Transceiver CC1120 of TI Chipcon,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.

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.

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.

Reason and Solution

Can’t communication

1.The power supply connect not well, check the module VCC whether it is out of maximum rating.

2.The signal line connect not well, check the module SPI interface.

3.The settings of the transmitter module and receiver module are not the same. Check these modules’ register configuration.

4.Signal block. If the transmitter work with a high TX power, and the receiver was put at a short distance(<0.5m), maybe there is a signal block to make no communication.

Communication distance is too short

1.The application environment is too bad or the antenna is shield. Put the antenna to a better place outside or higher throw a coaxial line , replace it with a higher gain antenna.

2.The work space contains a same frequency interference source, or a strong magnetic field interference, power source disturbance. Try to change the carrier frequency or get far away from the source of the disturbance.

3.The power supply is not strong. Check the voltage and the current whether it is enough.

High data error

1.The power supply ripple is too big, Change the power supply.

2.Check the module register configuration, it is recommended to set as the CC1120-datasheet.

3.There is a carrier frequency interference, change the channel.

4.The antenna unmatched to the module RF interface, change another matched antenna.
