CC1120: cc1120 rs test data receive err..

Part Number: CC1120

I made a module that uses 447MHZ same as ek board[Sub-1GHz Wireless Long Range Reference Design with CC1120 (420 to 470 MHz)].

The EMS Radiated Susceptibility Immunity Test failed at electric field strength 10V/m and success in 3V/m

Data is not received due to electromagnetic noise effects.

Is there anything that can change the settings in the schematic rf RLC value or register setting value?

  • 10 V/m is a very strong field. Have you done any calculations on what the input power will be on the antenna when you place the DUT in this field strength. As I have understood it tests with field is normally done to verify that the radio works after the fields is turned off.
