Part Number: LAUNCHXL-CC1350-4

HI, 

one of my customer put cc1350-4 LP as a bench mark reference for the 433MHz band. 

could you provide a test report of the band? tx power and sensitivity is okay.

    The performance in the 433 MHz band could be found in the datasheet. Since the launchpad has a switch that select either 433 MHz or 2.4 GHz the loss in this has to be taken into account when comparing the data. See also www.ti.com/.../swra543a.pdf

    www.ti.com/.../swra543a.pdf is exactly what we need. thanks.

    Hi TER,

    It's come from one project.

    http://www.ti.com/lit/an/swra543a/swra543a.pdf

    The sensitivity test on this board is -110dBm at 433MHz.

    We test the sensitivity of this board by default SmartRF Studio setting:

    The test result it worse than us. Is there any test condition different?

    431:-109(packet:33%,BER:0.83%)

    434:-104.5(packet:37.7%,BER:0.98%)

    438:-104(packet:24%,BER:0.57%)

    I find it strange that you get the expected value for the lowest frequency but not at the two others. Have you checked if you have a high background noise floor on these frequencies that could affect the measurements?
