Application of high temperature superconducting microwave devices in mobile communications

The rapid growth of the mobile communication industry has created a significant opportunity for high temperature superconducting(HTS) technology. The HTS base station subsystems composed of filters, low noise amplifiers and cryocoolers have superior characteristics and will bring dramatic improvements for mobile communications. A number of specialized companies have chosen to tie their fates to the development of HTS subsystems in commercial mobile communications. Nearly 2000 HTS subsystem products are currently deployed in the US.Subsystem prototypes in Europe and Japan have also been completed. The first demonstration of an HTS subsystem for mobile communications in China was made by the Institute of Physics, CAS, in early 2001.
