| Abstract | Until recently low noise figure mixer diodes for operation above 80 gc were very difficult to achieve and had short life times. This paper describes the procedures and results that evolved from a development program that eliminated these disadvantages. The three major areas to be investigated in developing a low noise figure diode were selection of an intermediate frequency for minimum crystal noise ratio, selection of a semiconductor material that gave low conversion loss, and mounting the diode such that package parasitics have a minimal effect. (The term low noise flgure in this discussion infers crystal noise figure, i.e.. the product of the conversion loss (Lc) and the noise ratio. It is assumed that tie noise figure of the IF amplifier, whether it be transistor, tunnel diode or TWT, will remain relatively constant through the low microwave frequencies. ) |

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.
