| Abstract | Novel SAW (surface acoustic wave) antenna-duplexers at 900 MHz and 1.684 GHz are presented. Each of the front ends consists of a transmitter path containing a SAW filter for noise suppression, a receiver path containing SAW filters and low-noise amplifiers, and a duplexing circuit. For the 900-MHz FDMA (frequency-division multiple access) mobile radio system the SAW filters must provide both filtering and diverging. The selectivity of the front end has been enhanced by a sophisticated design of the microstrip antenna terminal. For the European TDMA cordless telephone system, the SAW filters provide preselection and noise reduction, and pin-diode switching is used for time multiplexing. The transmitter path consists of three GaAs-FET low-noise driver amplifiers and the SAW filter. The selectivity of the receiver is enhanced by a stripline filter. The feasibility of the combination of SAW and microstrip technologies for the development of low-cost mobile radio units is demonstrated. Design, fabrication and performance of SAW microstrip front-ends in the low gigahertz range are reported. |

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.
