All-digital transmitters are gaining an increased research importance due to the unparalleled proliferation of dissimilar wireless standards and more recently due to the white space technology needs. In this paper, a new fine tunable multi-channel transmitter is presented. This new architecture supports concurrent multi-rate, multi-band, multi-standard transmission and significantly minimizes the output frequencies restrictions of current approaches by allowing fine frequency tuning for channel selection. The obtained results show the feasibility and potential of FPGA-embedded RF transmitters where the use of polyphase datapaths substantially improves the SNR of the desired signals.
