Development of a HTS transceiver sub-system for 3G mobile communication TD-SCDMA base station

Abstract

A prototype of a high temperature superconducting (HTS) transceiver sub-system for applications in a TD-SCDMA, one of the third generation (3G) communication standards, base station has been developed. Both the HTS sub-system and the conventional counterpart have been implemented into a TD-SCDMA commercial communication network and comparison test studies were carried out. The measured results showed that the HTS sub-system could remarkably improve the RF performance of both transmitting and receiving chains.

Progress on applications of high temperature superconducting microwave filters

“…The Institute of Physics, Chinese Academy of Sciences (IOP CAS) has developed a dual mode HTS microstrip patch filter with a handling high power up to 11.7 W [98]. Based on this filter, IOP CAS has constructed the world's first HTS transceiver for TD-SCDMA [99]. Field trials have also been successfully carried out in a commercial network by replacing the conventional transceiver with a HTS receiver.…”

Enabling High-Temperature Superconducting Technologies Toward Practical Applications

“…The Tianjin Hi-tech also conducted HTS subsystem field trial in CDMA base stations in Tianjin from 2004. Based on the success of constructing a HTS filter being able to handle up to 11.7-W power [126], the IOP CAS group constructed the world first HTS transceiver which works in the same frequency band to meet one of the 3G mobile communication standards, i.e., time-division-synchronous code multiple access (TD-SCDMA) [127].…”
