Influence of the Fabrication Process on the Performance of X-Band Filters

Abstract

Abstract-Growing demand for mobile and wireless communication systems has generated much interest in low-cost, high quality microwave fabrication technologies. The performance of these systems relies on not only excellent design and analysis but also the characteristics of materials and their corresponding fabrication technologies. Often the designer is faced with a compromise between satisfying the high performance demands of a microwave component, and achieving low fabrication cost. This paper studies feasibility of realizing microwave bandpass filters using thick film screen printing techniques. The measured and simulated results for a 9.5GHz edge coupled bandpass filter have been determined and compared.
