CC2500: PID for CC2500

Part Number: CC2500

Who can help? CC2500 provides PID file Thank you~

I used one of CC2500 for RF prediction, and the situation is as follows:

1) The power is low, about -7.5dB, and the online loss is about - 5~- 6dB, which is required by South Korea to be above - 5dB and needs to be rectified

2) How to switch a single carrier signal for a sample? If the carrier wave transmitted by the sample is used, the frequency offset is now offset from the center frequency by+180kHz, and the standard is offset from the center frequency by+120kHz

    Hi Bright,

    For the PID file. I'm not sure what is being requested here. What is a PID file? What is it used for or what are you attempting to do?

    For the low power question. If you believe there is a hardware issue with your design, you can follow the guidance at https://www.ti.com/tool/SIMPLELINK-2-4GHZ-DESIGN-REVIEWS to request a design review. 

    Please also verify that your register settings match the register settings provided by SmartRF studio for the target transmit power.

    For the last question, I'm don't think I understand the question. What I understand is:

    • You are trying to transmit an unmodulated carrier wave
    • You are measuring the frequency of the carrier wave to be +180kHz beyond the programmed center frequency?
    • I don't understand the third part about the 120kHz

    Can you provide a more specific example with the steps attempted, the actual values and the results?

    Thanks,

    Jake
