| Abstract | In this paper a novel concept for the realization of a highly integrated receiver frontend is presented. The frontend consists of a forward coupler to split the low frequency path (0–43 GHz) and the high frequency path (43–67 GHz), a mixer for the down conversion of the high frequency input signal and a magnetically tunable filter to achieve a high supression (>60 dBc) of the image frequency and all other higher order intermodulation products emerging in a non ideal mixer. The combination of the mixer and the tunable filter, both realized in finline technology, and a forward coupler based on microstrip lines allows for assembling a receiver frontend without any substrate interconnects in the high frequency path. This makes it possible to circumvent reflection losses caused by such interconnects thus achieving a conversion loss of the complete frontend of less than 17.9 dB in the frequency range from 43 to 67 GHz. By taking advantage of the cutoff-frequency of the used finline circuits a suppression of more than 60 dBc of the image frequency and all the other spurious mixer responses can be guaranteed. |

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.
