| Abstract | In recent time, class-EF power amplifiers are promising for the high power added efficiency (PAE) by turning output matching network (OMN) to control the even and odd harmonics at the drain. High quality factor (Q) of output matching network in the circuit is required. So it is difficult to design a broadband high efficiency power amplifier. A practical method of broadband design by using microstrip radial stub instead of normal open or short stub is proposed in this paper. A compact OMN topological structure is also proposed to reduce the size of circuit. Simulation results show that proposal class-EF GaN HEMT power amplifier has PAE of more than 60% and bandwidth of 850MHz from 1.7GHz to 2.55GHz. The output power is from 41.5dBm to 42.5dBm. |

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.
