IWR6843ISK-ODS: TI ISK-ODS ES2 signal integrity test

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: IWR6843,

Hi TI members,

After we made our PCBA with IWR6843. we want to test Radar signal integrity

such as phase noise, EIRP, etc.

Do you have the phase noise, EIRP, chirp, Beamwidth suggestion spec?

For example, IWR6843 phase noise is -92 dBc/Hz. but the phase noise doesn't show from min to max range.

Hi Max,

I've asked an expert to look into this and we should have an answer for you in the next few days.

Cheers,

Akash

Hello,

You could refer to the EVM user guide Section "3.6 IWR6843ISK-ODS Antenna".

This provides the Antenna radiation pattern measurements.

Tx and Rx antenna gain is in the vicinity of 6-7dBi. And IWR6843 Tx output power is 10 dBm typical.

Phase noise spec doesn't change with the ODS antenna configuration, Datasheet numbers should still hold good.

Currently, data-sheet spec is available only for Nom condition.

Thanks and regards,

CHETHAN KUMAR Y.B.
