| Abstract | A 240 GHz homodyne circularly polarized SiGe FMCW radar transceiver module with a single on-chip antenna is presented. The transceiver chip is implemented in a low-cost 0.13-μm SiGe HBT technology version with cutoff frequencies $f_{T}/f_{max}$ of 300/450 GHz. The transmit block comprises a wideband ×16 frequency multiplier chain, a 4-stage PA, while the receive block consists of a 3-stage PA acting as a preamplifier with high linearity, a fundamental down-conversion mixer, and a 4-stage PA to drive the mixer. A Gysel power splitter, a coupled line quadrature hybrid coupler, and a dual polarization on-chip antenna are added on-chip to realize a fully integrated radar transceiver. All building blocks are operated differentially. The use of a single antenna in the circularly polarized radar transceiver leads to compact size and high system SNR. The measured peak radiated power from the lens-packaged radar module is +5dBm and the SSB noise figure is 21 dB. The characterization bandwidth of the radar transceiver is 54 GHz around the center frequency of 240 GHz, and the simulated Tx-to-Rx leakage is below -23 dB. After system calibration the range resolution of 2.75mm is achieved, which exactly corresponds to the theoretical BW-limited resolution value. |

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.
