Case Study for Mobile Communications Applications Microstrip filters play various roles in wireless or mobile communication systems. This chapter is particularly concerned with a case study of high-temperature superconducting (HTS) microstrip filters for the cellular base station applications. The study starts with a brief discussion of typical HTS subsystems and RF modules, including HTS microstrip filters for cellular base stations. This is followed by more detailed descriptions of the developments of duplexers and preselect bandpass filters, including design, fabrication, and measurement. . | Microstrip Filters for RF Microwave Applications.

The work presented here has been carried out mainly for a European research project called Superconducting Systems for Communications SUCOMS in which the authors have been involved. The project is funded through the Advanced Communications Technologies and Services ACTS program. It involved a number of companies GEC-Marconi UK Thomson-CSF France and Leybold Germany the University of Birmingham UK and the University of Wuppertal Germany. The objective of the project was to construct an HTS-based transceiver for mast-mounted DCS1800 base stations. HTS SUBSYSTEMS AND RF MODULES FOR MOBILE BASE STATIONS The technology and system challenges of next generation mobile communications have stimulated considerable interest in applications of high-temperature superconducting HTS technology 1-7 . The challenges for cellular mobile base stations vary but may focus on increasing sensitivity and selectivity Sensitivity The benefits of increasing sensitivity in rural areas is obvious since the number of mobile base stations and thus the investment necessary to secure the radio coverage of a given area will be reduced as the range of each 433 434 CASE STUDY FOR MOBILE COMMUNICATIONS APPLICATIONS mobile base station .
