| Abstract | A 60 GHz MMIC dual-quadrature mixer (DQM) has been designed, fabricated in a commercial pHEMT MMIC process and characterized with probed measurements. A measured down conversion loss (L/sub C/) of 8.5 /spl plusmn/ 1 dB over the frequency range 47 to 67 GHz is obtained with an LO to RF isolation better than 20 dB and 8 dBm of LO power. Measurements verify that the IF bandwidth is truly ultra wideband with a total IF bandwidth of 11.5 GHz. Thus, with a fixed LO signal of 58 GHz, the RF band between 53 and 64.5 GHz can be down converted directly to the base band while maintaining a high LO to RF isolation. Single resistive mixers are used for the actual down conversion which results in a high IIP3 figure of 20 dBm and virtually no DC power consumption. Furthermore, the DQM exhibit very low reflection coefficients at the RF and LO ports due to the dual-quadrature topology. |

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.
