利用时变传输线的参数放大和混频效应，设计了两个单片集成参数混频器。不像传统的无源混频器，这些参数混频器可以提供一个温和的转换增益，同时实现低噪声数字。所设计的行波ttl参数混频器在2.3 GHz到2.9 GHz范围内的平均转换增益为0.4 dB。测量带宽内的平均噪声系数为2.0 dB，输出P1dB和IP3分别为11.8 dBm和22.0 dBm。此外，还设计并制作了一种输出反射式ttl参数混频器。测量结果表明，通过反映信号频率和本LO泵浦频率处的功率，可以显著提高转换增益和本LO功耗。
Parametric amplification and mixing effects of the time-varying transmission line (TVTL) was applied to design two monolithically integrated parametric mixers. Unlike traditional passive mixers, these parametric mixers can provide a mild conversion gain while achieving a low noise figure. An average of 0.4 dB conversion gain was obtained from 2.3 GHz to 2.9 GHz at the output of the designed traveling-wave TVTL parametric mixer. The mean noise figure within the measured bandwidth was 2.0 dB, and the output P1dB and IP3 were 11.8 dBm and 22.0 dBm respectively. Furthermore, an output-reflected TVTL parametric mixer was also designed and fabricated. The measured results indicate that both the conversion gain and LO power consumption can be significantly improved by reflecting the power at the signal frequency and the LO pump frequency.
