LAUNCHXL-CC1312R1: CC1312R1

Part Number: LAUNCHXL-CC1312R1


Tool/software:

Hi

My name is Kevin Hwang in South Korea.

Currently, I am developing a sensor monitoring system (sensor nodes and gateway) using the CC1312R1.

The frequency band we intend to use is 940.1MHz to 946.3MHz.

Using the LAUNCHXL-CC1312R1 Evaluation Board and SMARTRF_STUDIO 7, I measured the output power with a spectrum analyzer,

and even when setting it to 14dBm, it only reaches about 11dBm.

Do you have any information on the RF Matching Value to support the 940MHz band?

If not, could you explain the RF Matching method?

Thank you.

    Hi Kevin,

    Just to align the measurements.

    Can you measure the output power at 868 MHz and 915 MHz to see if this correlates to the expected output power settings before we start to tweek the design to 940 MHz ?

    Thanks.

    Hi RGW.

    SMARTRF_STUDIO 7 tool cannot adjust the channel power in the 940MHz band,

    and is only set to 13dBm. At this time, the output power is only about 11dBm.

    We will check the power settings using a method other than the tool(SMARTRF_STUDIO 7) and then contact you again.

    Thank you.
