| Abstract | In this paper, a two-stage cascaded power amplifier (PA), which consists of cascode topology, for ultrawideband (UWB) systems operating in the 3.1-4.8 GHz frequency range is presented. The shunt-shunt feedback is used to arrive at wideband matching. A three-section ladder output network is exploited to achieve excellent output match in a wideband fashion and to optimize the power performance. The PA is implemented by TSMC 0.18mm mixed signal/RF process. The measured results show the following performance: S21 of 20.7-dB, more than 10-dB input and output return loss, 5.8% maximum power-added-efficiency and 2.57dBm output $P_{1dB}$ with 15.57dB power gain at 3GHz |

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.
