AWR1642: The attenuation at cutting edge of LPF in 1642

Adam Yao94020

Part Number: AWR1642

Hello,
Do we have the attenuation plot (or attenuration values) of AWR1642's LPF? For example, if we use IF BW as 5MHz, and setting ADC sampleing rate as 6.25Msps, what is the LPF's attenuation value at 6.25Msps?

Thanks,
Adam

Hello Adam,

Attached is the filter response for 5Msps (pass band is 4.5 Mhz). At 5Mhz the filtering is >60dB. So for a 6.25Msps case this would happen at 6.25Mhz.

Regards,

Vivek
