AFE7920: RF & microwave forum

Part Number: AFE7920

Hi,

I am trying to design AFE7920 in RU system.

Do i also need ADC driver for AFE7920?

Also, I wonder why we use wide band ADC driver in RX and use narrow band ADC driver in TX.

Thanks,

Yun

    Hello Yun,

    Please submit a request to get more information on the AFE7920 support collateral

    1. go to AFE7920 website 

    2. click on request information. You will received a link from mysecuresoftware from TI after you have been approved.

    The AFE7920 have build in RF sampling ADCs for traffic receivers and feedback receivers for DPD.

    I am not quite clear on the your question

    wideband ADCs are typically used for feedback receivers for DPD, while narrow band ADCs are used for traffic receiver.
