| Abstract: | In view of the analog front circuits′ restrictions on the performance and complexity of traditional Intermediate Frequency(IF) digitalizing transceiver,a Radio Frequency(RF) digitalizing scheme based on low-pass sample theory is introduced,in which Digital Up/Down Convert(DUC/DDC)are performed by GC5016.This paper focuses on the joint design of Cascaded Integrated Comb(CIC) and Programmable Finite Impulse Response(PFIR) filter in GC5016 through simulation research and hardware verification.The out-band rejection of the DUC/DDC is up to 100 dB,and band flatness is limited to 0.1 dB,so,the design fully satisfies the HF transceiver′s requirement. |
