| Building on the experience of the SMA project, we have developed our own expertise in the instrumentation of sensitive radio-wave receivers. Our routine work involve projects in the area of cryogenics, quasi-optics, microwave and mm-wave devices, analog and digital electronics, precision mechanical design and machining. In particular, we have been in pursuit of two important topics to be our core technologies─superconductor-insulator-superconductor (SIS) junction design and fabrication, and complex receiver system design and integration. We have established stable Nb-based SIS mixer fabricating process. High performance SIS mixers covering frequency range of 100-900 GHz have been developed. |
