AWR1243: AWR1243 Tx fast switch On-off isolation

Hi Adam,

AWR team should have an answer for you in the next couple of days.

Cheers,

Hi Akash,
Do you have any update to this problem?

Thanks,
Adam

Hi Adam,
Sorry for the delayed reply.

Can you please elaborate more on what you mean by "bottom signal power on the RF output pin when we turn off the RF output. " ?

-Raghu

Hi Raghu,
It is the floor noise on the RF output pin when it is turned off.

Thanks,
Adam

Hello Adam,
In our normal chirping operation the TX is turned ON during the sampling window and turned OFF otherwise.

All our measurements are based on when the TX is turned ON.

Do you know the reason why the customer is asking for such data ?

-Raghu

Hi Raghu,
They don't tell the exact reason, but they said they find this parameter in other vendor's datasheet.

Thanks,
Adam

Hi Brian,
   Many thanks for your reply.
   Customers said this parameter has impact to the phase noise performance, but they did not give a comment whether our spec is enough.

Best regards,
Adam
