| Abstract | This paper proposes a dual-band predistortion power amplifier using diplexer for digital cellular (f/sub 0/=880MHz) and IMT-2000(f/sub 0/=2140MHz) base station. Each high power amplifier is linearized by using predistortion method. The implemented predistorter uses reflection type IM generator with 3dB hybrid coupler for good reflection characteristic. The diplexer is composed of low pass filter using defected ground structure(DGS) microstrip line and high pass filter using high-Q lumped capacitors and distributed elements. For a forward link one-carrier CDMA IS-95 and WCDMA signal, the proposed dual-band predistortion power amplifier shows ACPR improvement of about 10dBc and 9.36dBc for cellular and IMT-2000 band of operation, respectively. |

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.
