对肖特基势垒变容乘法器的性能进行了比较，重点介绍了在1太赫兹以上频率下产生功率的情况。800 GHz的测量效率在1.13 THz时大于3%，在1.4 THz时下降到0.9%，在1.4 THz时下降到0.25%。链中倒数第二个乘法器的可用功率对最后一级的输出施加限制。进一步的工作还需要克服乘法器结构中的损耗，并更好地理解变容管中的速度和电压饱和效应。
The performance of Schottky barrier varactor multipliers is compared, with emphasis on generating power at frequencies above 1 THz. Measured efficiencies at 800 GHz are greater than 3 percent at and decrease to 0.9 percent at 1.13 THz and 0.25 percent at 1.4 THz. The power available from the penultimate multiplier in a chain imposes a limit on the output from the last stage. Further work is also required to overcome losses in multiplier structures and to understand better velocity and voltage saturation effects in varactors.
