| Abstract | A high ratio Wilkinson power divider is produced by cascading low ratio dividers. Combining two 1:2 and one 1:3 divider results in a 1:8 ratio. Theoretically the 1:8 divider has an S21 of -0.51dB and an S31 of -9.54dB. Under simulation the average S21 over a 1.7-2.7GHz band was -0.7dB and the S31 -10.3dB. A prototype was built on standard 1.6mm FR4 substrate. The 1:3 divider uses stacked substrates. Doubling substrate thickness allows a high impedance line to be realized at a sensible width. The measured average S21 was -1.6dB and the S31 -11.2dB. The FR4 substrate has an estimated loss of 1.4dB. Allowing for this loss, the power divider is operating close to the theory. |

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.
