在240 GHz载波频率下，使用基于mmic的直接转换射频前端，成功地演示了40米距离上的超宽带毫米波无线数据传输。新一代64GS/s富士通DAC评估板为QPSK和8-PSK调制基带信号提供64Gbit/s和96Gbit/s数据速率。根据误差矢量大小（EVM）测量来评估链路的整体性能。对于QPSK和8-PSK数据传输，EVM测量值分别为23.7%和21.6%。
Ultra-broadband mm-wave wireless data transmission at 240 GHz carrier frequency is demonstrated successfully over a distance of 40m using a direct conversion MMIC-based RF front end. A new generation 64GS/s Fujitsu DAC evaluation board provides 64Gbit/s and 96Gbit/s data rates for QPSK and 8-PSK modulated baseband signals. The overall link performance is evaluated in terms of error vector magnitude (EVM) measurement. For the QPSK and 8-PSK data transmission EVM measurement shows values of 23.7% and 21.6%, respectively.
