用于空间受限低温装置的高效射频滤波器
Efficient Radio Frequency filters for space constrained cryogenic set-ups
摘要:
噪声滤波是在极低温度下测量量子现象的重要组成部分。在这里,我们提出了一种滤波器的设计,它可以安装在空间受限的低温环境中包含大量的信号承载线。我们的滤波器具有65 kHz的-3db点,其在GHz频率下的性能可与最好的RF滤波器相媲美。
英文摘要:
Noise filtering is an essential part for measurement of quantum phenomena at extremely low temperatures. Here, we present the design of a filter which can be installed in space constrained cryogenic environment containing a large number of signal carrying lines. Our filters have a -3db point of 65kHz and its performance at GHz frequencies are comparable to the best available RF filters.
