Description | Author affiliation: Fac. of Eng. & Natural Sci. - FENS, Orhanli - Tuzla, Istanbul, Turkey (Dinc, T.; Kalyoncu, I.; Gurbuz, Y.) || IHP, Frankfurt (Oder), Germany (Kaynak, M.) This paper presents the building blocks of an X-Band T/R module in a 0.25 μm SiGe BiCMOS technology for phased arrays. The T/R module consists of a T/R switch, two SPDT switches, a power amplifier, a low noise amplifier, a phase shifter and a variable gain amplifier (not presented). The T/R switch, SPDT switch and the phase shifter are implemented using CMOS transistors whereas the PA and LNA are based on SiGe HBTs. The designed T/R switch achieves minimum insertion loss of 2.1 dB, an isolation of 42 dB and has an input $P_{1dB}$ of 27.4 dBm at 10 GHz. The SPDT switch has less than 2.2 dB loss at X-Band. The PA resulted in a small-signal gain of 25 dB and a saturated output power of 23.2 dBm with 25 % PAE. The LNA has 1.65 dB noise figure (mean) with a gain more than 19 dB at X-Band. Lastly, the phase shifter achieves simulated RMS phase and gain errors of 1°-3.5° and 0.8-1.8 dB at X-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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
