About the Monograph

For the growing need in wireless spectrum by wide bandwidth applications such as ultra-high data rate transfer, at speeds of 10 Gbps and up, millimeter wave plays important role in providing reliable spectrum solutions. Worldwide R&D in millimeter wave area has demonstrated many successful tests to establish the technology with its promising potential for the future of defence and security.

This monograph explores the design and implementation of millimeter wave active/passive circuits and systems using waveguide/MMIC (Monolithic Microwave Integrated Circuit) and planar waveguide technology. Extensive use is made of photographs of systems, line diagrams showing various techniques, and important system characteristics.

It begins with an introduction to frequency bands, unique millimeter wave applications in communication. It presents detailed discussions about millimeter wave devices and circuits, generating devices, e.g., IMPATT oscillators and Gunn oscillators, where concept of injection locking phenomenon in oscillators and power combining techniques, etc., have been highlighted. Receiver components, millimeter wave transceiver configurations and development of millimeter wave systems technology useful for defence services are presented. It also discusses future trends and technology challenges which enlighten about exploitation and challenges of millimeter wave frequency spectrum in futuristic military applications such as broadband communication technology, optical technique of millimeter wave generation with low phase noise signal for applications in imaging and phased array radar systems and millimeter wave options for mobile cell phones.

The book is written to support and supplement millimeter wave and subsystems/system courses of scientific institutions/university as well as a reference for researchers, professionals, and high RF frequency design engineers working in this exciting field of millimeter wave technology.

About the Author

Shri Awadhesh Kumar Shukla is Former Scientist 'G', Defence Electronics and Applications Laboratory (DEAL), DRDO Ministry of Defence. His education include BSc (PCM) in 1974 and BTech (Electronics & Telecommunication) from J.K. Institute, University of Allahabad, in 1978; and Fellow, Institution of Electronics and Telecommunication Engineers (IETE), New Delhi.

He joined DRDO in 1979, and contributed significantly in nurturing the millimeter wave technology, through Indigenisation of Millimeter Wave Components. He developed 140 GHz components and demonstrated passive millimeter wave imaging using indigenised components first time in the country. He designed and developed successfully Ka-band ground segment communication technology for defence forces and also developed high power solid state/magnetron-based transmitter front-end receiver at millimeter frequency for radar applications as a part of missile guidance unit. As DRDO Program Manager for indigenisation of devices and circuit components from industry, he indigenised these passive/active components and developed no. of indigenous vendors in the country for development of millimeter wave components.

He published 35 research papers in international and national journals. He received IGMDP Award for significant contribution in NAG Seeker Head; Technology Group Award for Development of Millimeter Wave Subsystems/System; and Laboratory Award for Development of Low Noise Amplifier.
