Part Number: AWR2243

Hi Experts,

According to an application note "Cascade Coherency and Phase Shifter Calibration" www.ti.com/lit/spracv2, it says below.

Could you please let us know about the RF frequency range of interest for the sensor?
For example,
Mode1: 76 to 77GHz (BW=1GHz), Mode2: 77 to 79GHz (BW=2GHz), Mode3 76 to 81GHz (BW=5GHz)
If there are some different start freq., center freq., and BW settings, does the calibration have to be done for each?

Thank you for your kind check.
Best regards,
Hitoshi

Hello Hitoshi San,

"RF frequency of interest" means the RF frequency range the customer is using in their chirp configuration. For example if they are using 76 .1 to 76.7 Ghz bandwidth then they can restrict the calibration to this frequency range. This is done using the "AWR_CAL_MON_FREQUENCY_TX_POWER_LIMITS_SB" API.

Regards,

Vivek
