Zusammenfassung:	A demonstration sub-system for mobile communications was developed. In this system, a high-temperature superconducting (HTS) microstrip bandpass filter on r-plane sapphire substrate was designed to have a quasi-elliptic function response, which was aimed at covering the whole receive band of DCS 1800 base station, i.e. 1710-1785 MHz. This filter was then integrated with a low noise amplifier (LNA) and a pulse tube cryocooler, forming a demonstration sub-system. Satisfactory performance of this system was achieved.
