Kythrion IC

Chief Commercial Officer at Circuits Integrated

Kifisia, Attica, Greece

About

Kythrion is Circuits Integrated Hellas' flagship antenna chip platform engineered to revolutionize satellite communications through advanced 3D heterogeneous integration of III-V semiconductors (GaAs, GaN) and silicon CMOS technologies. Designed for Ka-band and higher frequencies, Kythrion consolidates multiple discrete components—power amplifiers, phase shifters, low-noise amplifiers, switches, and RF routing—into a compact, highly integrated system-in-package (SiP) or antenna-in-package (AiP) architecture. This co-designed approach delivers up to 60% reduction in antenna size, weight, and cost while maintaining superior RF performance, signal integrity, and power efficiency compared to traditional PCB-based phased array solutions. Kythrion addresses critical market demands for LEO/MEO satellite constellations, enabling faster deployment, lower launch costs, and mission flexibility. The platform targets VSAT, flat-panel antenna (FPA), and next-generation electronically steerable antenna (ESA) applications across satellite broadband, 5G, IoT, and defense sectors. Currently advancing through TRL6-7, with commercial samples planned for Q2-Q3 2027, Kythrion represents a foundational technology enabling reduced-SWaP-C satellite communication systems and positioning CIH as a strategic partner for integrators and constellation operators seeking advanced, cost-effective antenna solutions
