Design and implementation of a direct RF-to-digital UHF-TV multichannel transceiver

This manuscript presents the design and implementation of a direct UHF digital transceiver that provides direct sampling of the UHF-TV input signal spectrum. Our SDR-based approach is based on a pair of high-speed ADC/DAC devices along with a channelizer, a dechannelizer and a channel management unit, which is capable of inserting, deleting and/or conmuting individual RF-TV channels. Simulation results and in-lab measurements assess that the proposed system is able to receive, manipulate and retransmit a real UHF-TV spectrum at a negligible quality penalty cost.
