Abstract | Although the Marchand topology has been used extensively to implement wideband baluns, its size is prohibitively large at low frequencies. Several methods have been proposed in the past to reduce the balun size, but they also result in a reduction of the percentage bandwidth. This paper presents an approach to implement compact wideband baluns, by employing two additional lumped reactances at the output of the Marchand balun. A design methodology for the baluns is proposed that allows simultaneous optimization of size and bandwidth. Using a multilayer LCP packaging technology, a wideband balun operating in the 5GHz band has been designed and fabricated. Measurements show a percentage bandwidth of 53% centered around 6.2GHz (for S11 < -10dB) at the same time effecting a size reduction of 64% over a conventional Marchand balun. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
