We are looking to use the ADS54J60 dual channel ADC in a future design.  What is the recommended buffer amp for the RF input into the ADC?

Thanks in advance,

Herb

    Herb,

    There is a reference design board from TI called the TSW54J60EVM which has a fixed gain amplifier (LMH3401) and a VGA (LMH6401) connected to an ADS54J60. You can order this board and download documentation from the TI website regarding this board. What IF do you plan on using? How much gain do you need?

    Regards,

    Jim

    OK, thanks for the info! We are not sure about the IF yet...still in planning mode for that. We need around 25-35dB of gain prior to the ADC.

    Thanks!
