AWR1243BOOST: Error found when postprocessing Raw_X.bin file

AWR1243BOOST: What is suggested chirp config for the max SNR?

Part Number: AWR1243BOOST
Other Parts Discussed in Thread: AWR1243

1/When RF Gain select sets 34dB and RX Gain sets 48dB, will the receiver signal be compressed?


2/for AWR1243 BOOST， start frequency =77GHz， we config full ADC samples, Pwr Backoff =0.
 When we process the data, comparing 15MHz IF band configuration (full sample rate) to 10MHz IF band , it seems signal attenuats seriously.


(1)Does different  IF band result in different SNR?

(2)Or any other  possible reason, like channel leakage for different IF band?

(3)What is  suggested chirp config for the max SNR?

    Hi,

    For this please look at the datasheet P1DB plot (page-21) for Q-1

    Q-2 Could you share the ADCData/Plot?

    (1)Does different  IF band result in different SNR? :: Not significantly. 

    (2)Or any other  possible reason, like channel leakage for different IF band? :: No.

    (3)What is  suggested chirp config for the max SNR? :: Follow app-note (section 2.1) where the radar equation has been provided. (Note that you can increase chirp time (T_r) to improve SNR.

    Regards,
