AWR1843: How long does it take to warm up

Raeseung Park
Prodigy 10 points
Part Number: AWR1843

Hello,

We are seeing an issue where RF power is not sufficiently saturated for several minutes after power on and initialization(at Room Temp.). but it operates normally after about 10 minutes.

about warm up time, I have a few questions.

1. Specifications for warm up time

2. Can PA and LNA calibration be performed for each frame?

3. Have you ever received a report on temperature characteristics issue?

4. Do you have ant ideas for this issue?

thanks.

    Hello Raeseung,

    There is no "warm up time" as such needed for the AWR1843 device. The Tx o/p would be set right from the first frame.

    Could you provide more details about your observation? Are you using a  board you have designed or are you using the TI EVM? What SW / application are you running on the AWr1843 device?

    Regards,
    Vivek
