| Abstract | A miniaturized and high stopband rejection bandpass filter(BPF) with three finite transmission zeros is presented in this paper. The BPF with a central frequency of 3.2 GHz and 200 MHz bandwidth is implemented in a novel distributed stripline configuration using LTCC (low-temperature-cofired ceramic) technology. A distinct feature of this filter is excellent out-of-band attenuation performance. The lower skirt of the passband is very steep. There is 34.6dB attenuation at 3.0 GHz, the input/output VSWR is less than 1.4. We employ Z-shape layer to produce the lower 2 transmission zeros. By properly controlling the cross-coupling between the second and the fourth resonator, transmission zero in higher skirt of the passband will be generated. Measurement results of mass production are shown to match well with the electromagnetic simulation, which validate the proposed structure. The overall size of the filter is 4.8mm×4.2mm×1.5 mm. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
