Negative, Mark.
The ADC14L020CIVY was an example of a general-purpose ADC on a board of my own design as pictured above.
As a general rule, a raw ADC will work from DC to the design maximum sampling frequency. In this case the older ADC14L020 will happily sample up to 20 MSPS (Nyquest max in of 10 MHz). However, an ADC does not operate in isolation. The self-designed filter circuitry that appears between the signal of interest and the ADC can have a profound impact on the ADC bandwidth. In my PCB there is a toroid transformer which would prevent DC measurement.
The pictured DGPS board was part of a project I constructed long ago. It worked, but is not optimal, and not for sale. There are better solutions. Recommend you explore the ADC options with the team designing your RF front end. Close integration of the amplifier, filter, and ADC will likely yield the best results.
Sincerely,
Aaron
