| Abstract | In this contribution, the design of an uneven AB-C Doherty power amplifier (DPA) in GaN technology, implementing a new approach to control the higher device harmonics, is presented. The DPA was designed to operate at 2.14 GHz and with the aim to reduce as much as possible the chip size, without losing the Doherty operating principle. The measurement results in CW conditions at 2.14 GHz had shown average drain efficiency higher than 55% at 6 dB of back-off, with a saturated output power of 37 dBm. |

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.
