Abstract:

To improve the data transmission rate, in this paper a novel design and implementation of a highspeed interconnect system was proposed based on SIW(substrate integrate waveguide) using hexadecimal quadrature amplitude modulation (16QAM) technique. The inserted loss of the fabricated SIW is appoximately 0.5 dB within a bandwidth of 14 to 28 GHz; the maximum data rate of the 16QAM interconnection system is 20 Gb/s, and a clear eye diagram and constellation diagram is obtained through simulation in ADS(advanced design system). The data rate of the proposed 16QAM highspeed interconnect system is 4 times than that of the conventional system using highfrequency carrier modulate method. Therefore, the proposed 16QAM SIWbased system significantly improves the bandwidth efficiency of SIW and the data transmission rate of the interconnect system.

Key words: substrate integrate waveguide, hexadecimal quadrature amplitude modulation(16QAM), highspeed interconnect
