| Abstract | A MMIC 4-way phase splitter has been designed with phase and amplitude errors less than 20 and 0.5 dB respectively over the 0.7÷3 Ghz band. The circuit consists of a 2nd order all-pass RC network and a pair of differential chains which provide four signals with 0°, 90° 180° and 270° relative phase shifts and equal amplitude. Passive all-pass networks were studied decades ago, but their wide-band, tolerance-resisting behavior hasn't been proved until their monolithic implementation. On the other hand, MMIC GaAs FET's differential amplifiers have been less studied and a new systematic and efficient design technique has been developed and applied to this module. The circuit, with dimensions of 1700×2200 ¿m, has been fabricated using the GEC-Marconi GaAs foundry F20 process and the measurements confirm its good properties over the entire frequency band. |

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.
