Company information
Morita Tech has been an innovation company since its founding, utilizing four solution capabilities: "5G," "EMC," "Shielding," and "High Frequency," to continuously realize products and technologies that solve challenges in various industrial businesses. In recent years, we have developed a "Compact OTA (Over The Air) Testing Environment" equipped with a short-range transmission and reception device called "Antenna Coupler," which has received great acclaim from telecommunications carriers and local 5G operators, and has been widely adopted in their "labs." In local 5G, it is used as a desktop OTA testing environment and interoperability testing system for the development and verification of base stations and terminals utilizing open source. Additionally, our product lineup includes various solutions as applied products for EMC visualization solutions aimed at achieving carbon neutrality (decarbonized society), such as "visualization of secondary batteries, visualization of partial discharge, and visualization of transient noise." We have four core departments and technologies in-house: "Mechanical and Structural Design," "Electrical Design," "Software Development," and "Manufacturing and QA," and we are fully committed to meeting our customers' expectations and demands while building long-term mutual trust relationships with them.
