| Abstract | Low-cost hybrid-integrated surface acoustic wave (SAW) filter duplexers consisting of receiver top filter, transmitter final-stage filter and antenna terminal have been developed. The prototype designs were oriented at the GSM system specifications in the 900 MHz-band. Three-stage ladder-type SAW filters having 3dB-bandwidths of 44 MHz at their center frequencies of respectively 902.5 MHz and 947.5 MHz and an insertion loss of 1 dB have been designed to perform the duplexing function by the use of only one transmission line. Leaky SAW phenomena as well as parasitics of package and chip layout effects have thoroughly been taken into account, and a very good agreement between simulation and measurement has been obtained. In the transmitter (Tx) and receiver (Rx) path, the complete duplexer has respectively an insertion loss of 1.2 dB (Tx) and 2.1 dB (Rx) and a 3 dB-bandwidth of respectively 40.1 MHz (Tx) and 47.4 MHz (Rx). |

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.
