Ohmplus Technology

Phased array antennas are vital for modern communication technology. Ohmplus leverages expertise and the OHM⁺ Fast algorithm to create fast measurement and automatic calibration systems for phased array antennas. These systems find use in mass production testing for 5G, millimeter-wave, supply chain of semiconductor and low earth orbit satellite technologies, revolutionizing related industries.

Ohmplus’s system have the features of over 10 times faster than existing systems, automatic optimizing antenna elements without moving the testing antenna, and the antenna unit errors of up to 10% can be recovered under customer's shipment conditions. Therefore, customers do not need to build a huge inspection and maintenance team, and can take into account the quality and speed of shipments. In addition, its fast group testing system can test up to 32 RF chips or modules at once, surpassing market systems in speed and cost-effectiveness. Its total solution improves production efficiency and quality for phased array antennas and RF chips or modules, particularly aiding LEO satellite and semiconductor industries.
