RFHIC (CEO Deok-su Cho), a compound semiconductor specialist, announced on the 11th that it had been selected as a research and development institution for the 'Key Component Localization Development Support Project' promoted by the Defense Acquisition Program Administration.
This research and development project, totaling 7.6 billion won, including 5.7 billion won in government funding, aims to domestically produce a high-power amplifier for satellite terminals mounted on vehicles. This device is a key component that supports direct connection to satellites anywhere in the operational area, maintaining a stable communications network with the command center.
Through this project, RFHIC will develop a gallium nitride (GaN)-based solid-state power amplifier (SSPA) to replace the twin-wall tapered amplifier (TWTA) on a 1:1 basis, aiming for domestic production. The GaN-based SSPA will ensure stable operation even in the event of some failures, and RFHIC plans to develop a core component, the gallium nitride MMIC, in-house, thereby enhancing the defense industry's technological independence.
A company official said, “This project is a significant turning point that will increase the reliability of military communication equipment and realize the domestic production of core technologies,” and added, “As we have entered the military satellite communication system field based on the semiconductor technology we have accumulated so far, we expect large-scale mass production demand and market expansion in the future.”
He added, “We plan to expand the scope of technology applications beyond military equipment to civilian satellite communications, 6G communications infrastructure, and the space industry in general.”
