| Abstract | In this article, we proposed one simple method which achieves variable load impedance. By this method, without utilizing load pull tuner, the errors caused by various reasons, such as parasitic effect at the lumped components and active devices, can be corrected. We designed and fabricated one Class-AB amplifier to demonstrate our simple method by adjusting a shunt variable capacitor and inductor added at the input and output of the load matching network respectively. Before correcting the circuit, comparing the measured maximum PAE (Power Added efficiency) of the power amplifier (40.21% at 37.70dBm output power) with the simulated PAE (52.96% at 40.35dBm output power), the performance of this amplifier was not as what simulation predicted. After optimizing the circuit with our method, we obtained the maximum PAE reached 50.63% and the maximum output power increased to 40.10 dBm which more agree with the simulated result than the result before the correction. |

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.
