| Abstract | The performance of a compact power amplifier MMIC for 35 to 45 GHz applications is reported. Using a standard 6-inch, 0.15-/spl mu/m GaAs power PHEMT technology on 100-/spl mu/m substrate thickness, in combination with appropriate compact circuit topologies, this microstrip power amplifier achieved a linear gain of more than 24 dB over the 36 to 45 GHz frequency range. At 5 V and 500 mA bias, an output power at 1-dB compression of 26 dBm (P/sub -1 dB/=400 mW) was measured in the 37/spl sim/40 GHz band, with a saturated output power up to 0.5 Watt (P/sub sat/=27 dBm). The total chip size is only 3.6 mm/sup 2/ (2.4 /spl times/ 1.5 mm/sup 2/); compared to conventional power amplifier MMICs operating at these frequencies, the combined output power and gain densities per chip area are a factor two higher. |

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.
