我们报告的第一个演示便携式高温超导单片微波集成电路（MMIC）接收器前端模块上运行的商业小型制冷机。高温超导电路由一个阶跃边缘结混频器和一些高温超导滤波器制作在一个单一的MgO基板上。高温超导MMIC电路与微型制冷机集成在一起。样品真空室、冷头、压缩机和冷却风扇都装在一个客户设计的便携式盒子中，尺寸约为350 mm × 350 mm × 250 mm。高温超导约瑟夫森结为基础的微波电路成功地运行在制冷机无屏蔽没有明显的性能下降。介绍了一种高温超导MMIC下变频器的紧凑型单元的设计与实现以及性能评估。
We report the first demonstration of a portable HTS monolithic microwave integrated circuit (MMIC) receiver front-end module operating on a commercial mini cryocooler. The HTS circuit consists of a step-edge junction mixer and a number of HTS filters fabricated on a single MgO substrate. The HTS MMIC circuit is integrated with the mini cryocooler. The sample vacuum chamber, cold-head, compressor and cooling fans are all packed into one customer-designed portable box of approximately 350 mm × 350 mm × 250 mm in dimension. The HTS Josephson junction-based microwave circuit operated successfully in the cryocooler unshielded without observable performance degradation. The design and implementation of the compact unit and performance evaluation of a HTS MMIC frequency down-converter are presented.
