Abstract:
A solution is to transmit the signals with a wireless emitting-receiving antenna set with a suitable bandwidth. This work examines several wireless baseband transmission systems in a short distance configuration, associated to the distance between the cryogenic and room temperature stages, for data rates in the range of a few Gbps.
It elaborates on four crucial issues:
•    the choice and study of the proper line codes to be used for baseband transmission of digital signals without the need for analogue modulations, such as Polar Return-to-Zero and Manchester encodings ;
•    the study and selection of ultra-wide bandwidth antennas with a focus on small size Antipodal Vivaldi Antennas and monopole antennas to meet cryogenic constraints ;
•    The study of the Bit Error Rate (BER) of the transmitting system. Two methods were developed to recover the digital output signals and minimize the BER.
•    The comparison between simulations and measurements to assess the performance of the overall system.
 
Key words :
Manchester encoding, Polar RZ encoding, wireless baseband transmission, near field, high-data rate, small size antenna, ultra-wide band, UWB, Antipodal Vivaldi antenna, Monopole antenna, superconducting electronics, RSFQ
