Jianghong Shi · International Electronic Elements · 2008
The paper introduced the features,and structure of AD6655 which was 14-bit analog-to-digital converter,and specially introduced the function and capability analysis of digital down converter(DDC) integrated in AD6655.The design of a digital repeater based on AD6655 was provided.The scheme based on IF-sampling was employed to fit for different digital repeaters in mobile communication system. The test showed that the EVM could satisfy all requirements.
