The purpose of this research is to realize a superconductiong receiver system in millimeter and submillimeter wave region, where all elements of the system are superconducting devices. The obtained results are as follows:1) Elements of the receiver system, i.e., a mixer, a local oscillator and an IF amplifier, are developed. For the mixer, we use the SIS mixer, whose fabrication technique is established with Nb/Pb Josephson junctions. A novel local oscillator is devised. The output power of the oscillator is about 1 <micro> W in the frequency range from 50 to 500 GHz, which is large enough for the local oscillator of the SIS mixer. The IF amplifier with new operation principle is also developed.2) For the construction of the system, an efficient coupling method between the mixer and the oscillator is developed. With this method, they are integrated, and the performance of the integrated circuit is studied experimentally.3) Performance of the present system is studied experimentally, and is evaluated. Future development for the multichannel system is also discussed.

本研究的目的是实现毫米波和亚毫米波区域的超导接收系统，其中系统的所有元件都是超导器件。得到的结果如下：1)开发了接收系统的组成元件，即混频器、本振和中频放大器。对于混合器，我们使用SIS混合器，其制造技术建立在Nb/Pb约瑟夫森结上。设计了一种新型的本振。在50 ~ 500 GHz的频率范围内，振荡器的输出功率约为1 <微> W，对于SIS混频器的本振来说足够大。并研制了具有新工作原理的中频放大器。2)针对系统的构造，提出了一种混合器与振荡器之间的高效耦合方法。用这种方法对它们进行了集成，并对集成电路的性能进行了实验研究。3)实验研究了系统的性能，并对系统性能进行了评价。对多通道系统的未来发展进行了展望。
