Abstract | A miniaturized microstrip triplexer with a common resonator has been proposed in this paper. By exploiting the variable frequency response of stepped-impedance resonator, the common resonator can be shared by three filter channels of a triplexer if its fundamental and higher-order spurious resonant frequencies are properly assigned. The proposed triplexer with a third-order Chebyshev frequency response at each channel is composed of only seven resonators. Moreover, extra matching network placed on the input port is needed for the conventional triplexer, but it is not needed for the proposed one. Experimental triplexer is fabricated and measured to verify the usefulness of the proposed concept. The measured results are in a good agreement with the simulated predictions. The size of the triplexer is only approximately 0.48 $lambda_{g}$ x 0.32 $lambda_{g},$ showing a very small size. |

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.
