G-band quad-port balanced multiplier with 111.27 mW continuous-wave output power
利用新颖的四端口平衡式二倍频原型,开发了215～230 GHz 频段的肖特基变容管倍频器,并具备更加优秀的变频效率和功率容量.同时,所提出的倍频架构能够实现奇次谐波和四次谐波的本征抑制,并且其中采用的二极管管结数量相对于传统平衡倍频结构提升了两倍.因此,这种四端口倍频电路可以实现更好的转换效率和双倍的功率处理能力.在室温下,当输入功率为196～340 mW 时,该倍频器具有约39.5%的峰值转换效率(@218 GHz),即使在较高的频率下,该倍频器也被证明是高功率太赫兹波信号产生的理想解决方案.
A 215～230 GHz Schottky varactor-based frequency doubler utilizing novel four-port balanced configu-ration has been developed with improved conversion efficiency and power-handling capability.The proposed dou-bler,featuring doubled number of anodes in conventional balanced ones,could inhibit the odd-and fourth-order harmonics.Thus,better conversion efficiency and doubled power handling capability could be achieved.At room temperature,the fabricated doubler exhibits a～39.5%peak conversion efficiency(@218 GHz)for an input power of 196～340 mW,which is proved to be a perfect solution for the generation of high power terahertz waves even at higher frequencies.
