介绍了用于 W 频段（75-110 GHz）的有源平衡倍频器的毫米波单片集成电路的设计和性能。八倍和十二倍的乘法器是通过 100 nm 栅长变质高电子迁移率晶体管技术实现的。采用了一种新颖的电路架构，该架构使用级联有源平衡倍频器和三倍频器级以及有源不平衡到平衡转换器，以便将非常宽带的操作与输出信号的高频谱纯度结合起来。在模块级别，12 倍频器在 78 至 100 GHz 频率范围内实现了 -1.5 dBm 的输出功率和 2.5 dB 的相关转换增益，对应于 24.7% 的相对带宽。在此频率范围内，不需要的谐波相对于第十二谐波被抑制至少 12 dB。 8 倍频器可实现 6.9 dBm 的输出功率、8.9 dB 的相关转换增益以及 84 至 101 GHz 频率范围内 13 dBc 的谐波抑制。
The design and performance of millimeter-wave monolithic integrated circuits implementing active balanced frequency multipliers for the W-band (75–110 GHz) is presented. The multipliers by eight and twelve are realized in a 100 nm gatelength metamorphic high electron mobility transistor technology. A novel circuit architecture using a cascade of active balanced frequency doubler and tripler stages in combination with active unbalanced-to-balanced converters is adopted in order to combine very broadband operation with high spectral purity of the output signal. On the module level, the multiplier by twelve achieves an output power of −1.5 dBm and associated conversion gain of 2.5 dB in the frequency range from 78 to 100 GHz, corresponding to a relative bandwidth of 24.7%. Within this frequency range, unwanted harmonics are suppressed by at least 12 dB with respect to the twelfth harmonic. The multiplier by eight achieves an output power of 6.9 dBm, associated conversion gain of 8.9 dB and harmonic suppression of 13 dBc in the frequency range from 84 to 101 GHz.
