With the continuous advancement of transmission data rate, high-speed electronic interconnections are extensively investigated in electronic and information engineering field. For a high-speed data transmission system, channel degradation may result in deterioration of communication quality of digital signals. In X-band and Ku-band, high-speed interconnected transmission systems using single sideband modulation were proposed in this paper, where Pseudo Random Binary Sequence data with 231-1 pattern was used as the signal source at the rate of theoretical maximum. With regard to the comparison between pristine and degraded channels, different Ball Grid Arrays high-frequency transmission channels were respectively fabricated and measured. Experimental measurements of channels demonstrate that failed solder balls would cause significant decrease of reflection and transmission parameters in Ku-band. Simulations of all system models indicate that excellent eye openings and low bit error rates could be obtained, although the eye height was deteriorated in those systems working in Ku-band. Based on experimental tests and simulations, the results of this investigation provide a better understanding and evaluating for the effects of degraded interconnection channel in high-speed data transmission systems.
