Abstract | This paper presents two designs of reconstruction comb-line filters with symmetrical input for a class-S power amplifier system operating at 450 MHz. The class-S amplifier architecture is intended for highly efficient power amplification with demanding requirements for the design of the reconstruction filter terminating the final stage that operates in the push-pull current- mode. According to the measured results, the compact coaxial filters have insertion loss of less than 1 dB for the differential mode, a 3-dB-bandwidth of 27 MHz and a second pass-band at 2.8 GHz. The device can handle up to 300 W of input power and is mechanically tunable over at least one octave. |

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.
