Developed RF/Microwave substrate

1 Developed RF/Microwave substrate

Flexible microwave substrates are extensively used for variety of high end microwave circuit applications such as high power solid state amplifiers, patch antennas, mobile base stations etc. Although large volume of these materials is being used for strategic applications in the country, the requirement is fully met through imports. Understanding the importance of indigenization of these strategic materials, DAE developed a dimensionally stable, planar and isotropic PTFE/ceramic composite laminates. Excellent RF performance was obtained in terms of output power, gain and efficiency during system level evaluation.
