Abstract

In this letter, we report the near quantum-limited performance of a 230 GHz endfire superconductor-insulator-superconductor (SIS) mixer utilizing a Nb/Al-AlOx/Nb trilayer. An important feature of this mixer is its use of a unilateral finline for the waveguide-to-planar circuit transition, which allows for a wide radiofrequency (RF) bandwidth, a simple waveguide structure with easy alignment, and for the mixer chip to be aligned along the optical axis. Each of these factors is beneficial in the construction of large-format focal plane arrays. We tested the new finline mixer from 210 to 260 GHz in a liquid helium cryostat at ~4 K. The best recorded noise temperature was approximately twice the quantum limit, which is comparable to conventional radial probe mixers. This suggests that endfire SIS mixers can be used in large format arrays, comprising 100s or even 1000s of SIS mixing elements, while retaining state-of-the-art quantum mixing performance.

具有近量子限制性能的230 ghz终末SIS混频器
在这封信中,我们报告了使用Nb/Al-AlOx/Nb三层的230 GHz端火超导体-绝缘体-超导体(SIS)混频器的近量子限制性能。该混频器的一个重要特点是它使用单边鳍线进行波导到平面电路的过渡,这允许宽的射频(RF)带宽,简单的波导结构易于校准,并且混频器芯片沿光轴对齐。这些因素中的每一个都有利于构造大画幅焦平面阵列。我们在~4 K的液氦低温恒温器中测试了210 ~ 260 GHz的新鳍线混频器。记录的最佳噪声温度约为量子极限的两倍,与传统的径向探头混频器相当。这表明终端SIS混频器可以用于包含100个甚至1000个SIS混频器元素的大格式阵列,同时保留最先进的量子混频器性能。

期刊介绍: The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
