Research

Our Research fields include design and manufacture of solid-state microwave integrated circuit, traveling wave tube amplifier high-voltage, high-power power supply, etc., and military radar sub-system development. The products are vertically integrated from hardware, software and institutional R & D. We also make strict requirements on ISO quality management and information security, and provide comprehensive and optimal solutions.
