Abstract | This paper reports DC and RF characteristics of a high-voltage planar GaAs MESFET. Its breakdown voltages are over 65V at off state (V/sub gs/ = -1.5V) and 30V at on state (V/sub gs/ = 0.5 V). Under 28 V drain bias and 1.9GHz input, the power density reaches 1.0 W/mm with greater than 14dB linear gain. The third-order intermodulation product is -34dBc with 1dB back off from 1dB gain compression. These results suggest that the planar GaAs MESFET may be used as high-power and high-linearity RF power amplifiers in wireless base stations. The planar structure also makes it highly suitable for low-cost mass production. |

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.
