Microwave Active Devices and Circuits for Communication

Subhash Chandra Bera received his B.Sc. degree (with honors) in Physics from Presidency College, Calcutta, and B.Tech. and M.Tech. degrees in Radio Physics and Electronics from the Institute of Radio Physics and Electronics, University of Calcutta. He also received a Ph.D. degree in Microwave and Antenna Engineering from Gujarat University, India. Since 1994, Dr. Bera has been with the Space Applications Centre, Indian Space Research Organization (ISRO), Ahmedabad, India, where he has been involved in the design and development of microwave circuits and systems for various INSAT & GSAT series of communication payload projects as well as GAGAN/IRNSS navigation payload projects. He has developed several state-of-the-art microwave subsystems that are operational in various Indian national satellites. His research interests include microwave active circuits in general and solid-state power amplifiers, channel amplifiers, linearizers, limiters, attenuator and equalizers, in particular for spacecraft use. Currently he is Division Head of Satcom and Navigation Systems Engineering Division, Space Applications Centre (ISRO), Ahmedabad and Associate Project Director of GSAT-24 & GSAT-31 Communication Payloads. He has authored about 25 research publications in international journals and presented numerous papers at national and international conferences and symposiums. He has also delivered invited talks in the field of microwave active devices and circuits at various workshops and symposiums. He has also been granted four patents.
