1995-1997 Scientist CEERI, Pilani, Rajasthan

Worked towards research & development of Microwave Tubes for Defense & Space applications. Worked in CEERI, Pilani (A CSIR Lab, Govt. Of India) as a Scientist during 1995-1997 and associated with Design and Development of TWTs for a Defense project (CC TWT for RADAR Applications) and design of SWS for Helix TWTs (Space TWT Project ISRO).

1997- 2017 Scientist SAC, ISRO, Ahmedabad

Working towards research, design, development and production of satellite equipments: EPC (satellite power supply), SSPA and TWTA (Satellite RF power amplifiers). Working in SAC, ISRO Ahmedabad as Scientist/Engineer and associated with the following activities for various Indian National Satellites programs. During the last 18 years, I have worked in the field of EPCs, SSPAs & TWTAs. I have been responsible design and development of a number of State of the art EPCs ranging from very low power to high power & high voltage with advanced topologies. I have also been involved in the indigenous development of Space TWTAs, Space SSPAs.
