DEHRADUN: An indigenous radio frequency power amplifier, which will help meet futuristic requirements of programmable radios, has been developed jointly by the Defence Research & Development Organization (DRDO) and the Indian Institute of Technology (IIT), Roorkee.
Radio frequency (RF) power amplifier is an electronic device that converts a low-power radio-frequency signal into a higher-power signal.
As per officials of the IIT-Roorkee, the amplifier will help meet the futuristic requirements of programmable radios being developed by Defence Electronics Application Laboratory (DEAL) of the DRDO.
These amplifier units have superior performance and beat many similar products from global manufacturers achieving high efficiency and gain while simultaneously considering good harmonic and intermodulation suppression, officials further said.
The designs have been simultaneously optimized for Size, Weight and Power (SWaP).
A research group led by professor Karun Rawat of IIT-Roorkee, and a group of scientists and engineers led by Pinaki Sen of DEAL have designed these amplifiers to be simultaneously able to fulfill the high-efficiency requirements (for thermal management) and good linearity for signal fidelity.
Speaking about the importance of the invention, Prof. Karun Rawat of the department of electronics & communication said, “Keeping in tune with India’s mission for technological upgradation, the current R&D feat of technology focus is a glimpse of the improvements to existing capabilities and also bringing up new capabilities.”
DEAL director Lal Chand Mangal stated, “With its charter to do research, design, and development, DEAL is geared up for the development of such futuristic technologies indigenously by involving academia and industry in a big way, to maintain and support India’s defence system.”
The lack of indigenous components poses a severe challenge to R&D organisations in integrating the entire defence equipment in a given timeline.
The improvement in efficiency will result in a significant amount of heat load reduction, which will facilitate easy integration in the programmable radio chassis in the required form factor, Prof. Rawat said.
The unit will be assembled with the indigenous radio units of DEAL and DRDO, and will be manufactured by private domestic partners for mass production.
IIT-Roorkee director Prof. Ajit K Chaturvedi said, “With Make in India emerging as a powerful beacon to guide the development of defence technologies, we need to synergise the strengths of the government research agencies, industries as well as academics institutions to make India a truly global player in major defence technologies and systems.”
