| Abstract | A single chip multiplier by eight (/spl times/8) MMIC for 52-62 GHz output frequency is presented. The multiplier consists of quadrupler stage followed by a high pass filter, an inter-stage amplifier and a doubler stage. The required output power is achieved by a two stage buffer amplifier on the output. An output power exceeding 7 dBm is achieved from 52 to 61 GHz. The rejection of the unwanted harmonics is better than 28 dB and the detected degradation of phase noise due to the circuit is less than 1 dB at 100 kHz offset from the carrier, compared to a theoretical value of 18.06 dB for a multiplier by eight. The bias configuration is optimized to reduce the number of the required bias voltages to three. The total power dissipation is 450 mW. The MMIC is designed and manufactured in a commercial 0.15 /spl mu/m PHEMT process from WIN foundry. To our knowledge this is the first reported MMIC multiplier by eight based on PHEMT technology. |

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.
