| Abstract | Low noise amplifier with switch can effectively solve the problem of the high level and the wide dynamic rang of the input signal in communication systems. This paper presents two types of C-band microstrip LNA circuits with switches. Both using two stages of amplifier and microstrip matching networks, one circuit realizes the adjustable gain about -4 dB to 19 dB, a gain deviation about ldB, noise figure less than 1.6 dB and the work bandwidth over 200 MHz; the other realizes the adjustable gain about -6 dB to 29 dB, max input power about 23 dBm, noise figure less than 1.5 dB, the max gain about 29 dB at 5.25 GHz, a gain deviation about ldB and the work bandwidth over 200 MHz. Additionally, comparisons between these two circuits and between the simulated and measured results are also presented. |

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.
