| Abstract | The authors present examples of how the following four functions can be implemented in phased arrays: the distribution of a frequency reference to provide a stabilized carrier signal in both transmit and receive (T/R) modes of operation, the distribution of baseband information from CPU (T/R modules) to T/R modules (CPU), the distribution of control signals for amplitude and phase control of active T/R modules, and optical signal processing that will lead to the removal of the burden of signal processing from the small area of T/R modules to the distribution networks. It is noted that optically fed phased array antennas using the T/R level data mixing are realizable up to Ka-band with today's photonic device technology; however, this architecture demands a change in the design topology of the MMIC (monolithic microwave integrated circuit) T/R modules. True time delays are integrated with the data signals in this architecture by combining the externally modulated FO (fiber-optic) links with the acoustic-optic beam deflectors, to avoid beam squint. Initial analysis indicates that, at present, the T/R level data mixing architecture is superior to the CPU level data mixing as the carrier frequency exceeds C-band for the directly modulated, and X-band for the externally modulated FO links.< |

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.
