Using of AD6654 in Software Radio Receiving System

摘要

Focuses on ADC and DDC block for wide-band multi-channel receiving system based on the software radio concept. Expatiates on the using of the new digital down converter—AD6654 in an Intermediate Frequency signal (IF) receiving system. And the other blocks on the proposed IF receiver front-end are also addressed. On the basis of AD6654, a digitized multi-channel receiving system is given. The initiation scheduling for AD6654 is also provided. At the end of this paper, the test result of the proposed receiving system is shown.
