AWR2243: Conversion loss of mixers.

Ryo SASAKI

Part Number: AWR2243

Dear TI Engineer.

I have a question about AWR2243.

Is there a conversion loss (like -6dB) in AWR2243's IF mixer?

We suspect IF mixer loss as the cause of the signal power being less than the theoretical value.

Best regards,

Ryo

Hello Ryo,

The whole Rx chain is taken together when you look at loss/gain. Based on the programmed Rx gain, the relationship between the signal amplitude at the Rx input and the signal level seen in the ADC (in the form of dbFS) can be found in the following e2e thread: https://e2e.ti.com/support/sensors-group/sensors/f/sensors-forum/916374/awr1642-question-about-adc-fs-and-dbfs-to-dbm-calculation?ReplyFilter=Answers&ReplySortBy=Answers&ReplySortOrder=Descending
