Microwave Tube Research and Development Centre

MTRDC


About Lab

Microwave Tube Research and Development Centre (MTRDC) was established on 30th October 1984 at Bangalore under Defence Research and Development Organisation (DRDO), Ministry of Defence, with a vision to grow as a major Centre for R&D in the field of microwave tubes required for radar and electronic warfare (EW) systems for armed services and as a national centre for R&D on microwave tubes for communication systems. Dr. MD Raj Narayan, Scientist ‘F’, posted from Defence Electronics Research Lab. (DLRL), Hyderabad, took over on 3rd August 1985 as its First Director.

MTRDC occupied the present technical accommodation within BE Complex in the year 1992. The Centre is co-located near the Microwave Tubes Division within the premises of M/s Bharat Electronics Limited, Bangalore, to facilitate continuous interaction between R&D and production teams and a smooth technology transfer process. The JC Bose Microwave Tube Facility was added during 2011. MTRDC residential campus (MTRDC Enclave) with about 45 housing units was built in HMT township, close to the Centre in 2004.

Initially, the focus was laid upon the Computer-Aided-Design (CAD) and microwave measurement facilities to establish a strong design capability for meeting the challenges of designing traveling wave tubes (TWTs) for transmitters of different radars and ECM systems and testing of TWT assemblies. Subsequently, the various aspects of microwave tube manufacturing viz microwave engineering, high vacuum engineering, mechanical engineering, high voltage engineering, brazing and welding technology, high emission density cathodes and material science have been mastered. In the recent years, the facilities and technology for high performance Electronic Power Conditioner (EPC) has been established. The technologies for TWTs and EPC have been synergized to develop compact Microwave Power Modules (MPMs) and transmitters for Defence systems. Excellent dedicated facilities and core competence in several specific areas for complete development of TWT, MPM and transmitter from design stage to fully engineered devices have been established. A number of helix- and coupled-cavity-TWTs, cathodes, EPCs, MPMs and transmitters have been successfully developed and production of some of these at BE and other private agencies have been carried out.

Limited series of production of S band CCTWT for 3d_CAR, X-band CC-TWT for MMR, MPM for Flight Level Radar of AKASH, MPM for Multi-beam Jammer, EPC for MPM, and cathodes has been carried out at PSU/ Private companies. Induction of MPM in AKASH is a major breakthrough in the achievement of the Centre. MTRDC works in close interaction with the production agency, M/s Bharat Electronics, Bangalore, and has strong linkages with other organizations like IISc Bangalore, BHU Varanasi, DAVV Indore, CEERI Pilani, BARC Mumbai, IPR Gandhinagar, LRDE, DARE, DLRL, DMRL, SSPL, RCI, TBRL, DLJ, and GAETEC to take advantage of their expertise in related areas.
