Dear:

Could you kindly help to give the means about Dual Band DDC?

Since from datasheet we only find the difference between ADC32RF83 and ADC32RF80.

Could you give more detailed information about Dual Band DDC?

Hi Satish:

I know from the datasheet I can see the difference about 83&80.

I want to know the detailed meanings about Dual-band, Single-band, and Wide-band.

We think the Dual-band DDC means is supporting receive two modulated signals with different Carrier frequency point in the ADC' effective bandwidth.

Is it right?

Pls. help to give more information about it.

Yes, with dual band you can down-convert from two different carrier frequency. please see description in the datasheet (SBAS774A) figure 96 & section 8.3.4
