Company profile
Ohmplus Technology Inc. focuses on high-efficiency RF and phased-array measurement technologies and provides integrated solutions that span R&D validation through volume-production testing. Its measurement and test approach is intended to help electronics and semiconductor companies shorten test time and reduce overall test cost as systems move toward higher frequencies and greater complexity. The company's portfolio centers on high-throughput measurement and modular system design, with OTA wireless testing, RF FEM group testing, and phased-array antenna development kits among its principal offerings. Its solutions serve RF IC, RF FEM, AiP, antenna, and module manufacturers, together with customers in communications, satellite, and system-integration industries. The OHM Fast OTA wireless measurement series supports OTA testing for antennas and AiP modules, including radiation-pattern characterization, beamforming-performance evaluation, and 5G NR OTA testing. With multi-band scanning and automated measurement control, the OHM Fast OTA series can be used for per-unit functional testing in mass production of phased-array communication and radar products as well as antenna tuning, beamforming calibration, and system-level OTA performance evaluation during R&D. The OHM Fast GT-S series is a multi-site ATE group-testing solution for RF FEM devices that combines Ohmplus' self-developed phase-distribution and RF-switching modules, supports 4-site or 8-site parallel testing, and integrates S-parameters, output power, EVM, mask, Wi-Fi, and Bluetooth testing. Using a PXI-based architecture and group-testing technology, GT-S is designed to provide high test throughput with reduced instrument configuration for final test of packaged RF FEM devices. Ohmplus also supplies phased-array antenna development kits and carbon-fiber composite CATR solutions for low-Earth-orbit satellite, B5G communications, defense, and RF semiconductor test supply chains, supporting next-generation high-frequency system development and measurement. Ohmplus uses its self-developed OHM+ Fast algorithm and hybrid signal technology to provide Fast Calibration, Testing, and Fast Group Test Systems for phased-array antennas, together with OHM+Fast-GT-S for RF semiconductor multi-site group testing. The company also provides specialized array-antenna system design services and customized production-line integration planning based on customer requirements. Its stated application focus includes low-Earth-orbit satellite ground stations, semiconductor testing supply chains, and millimeter-wave communications. Ohmplus Technology Inc. was established in 2021 as a technology-driven startup founded in Taiwan, originating from a value-creation project at the Graduate Institute of Communication Engineering, National Taiwan University. In 2020, the team received the Future Technology Award organized by the Ministry of Economic Affairs and the Ministry of Science and Technology for the project titled "Fast Calibration and Beam Positioning for 5G/B5G Millimeter-Wave Phased Array Antennas" and was invited to exhibit the technology at the Future Tech Pavilion in the same year. The company focuses on fast measurement and automatic-calibration technologies and systems for millimeter-wave phased-array antennas and on implementing those technologies in practical, production-ready testing platforms. Ohmplus describes its core mission around technical excellence, managerial efficiency, and sustainable operation, and says it continuously improves technical capabilities and management efficiency to raise service quality while pursuing sustainable development and social responsibility. Its competitive-advantage description highlights a doctor-level technical team, advanced technologies and product experience, and professional customized solutions and consultation. For phased-array antenna testing, the company states that its Fast Calibration and Testing solutions are intended to improve product yield while reducing testing time and production cost, and that its technical structure is designed to be concise and lower-cost so it can match different production lines and customer needs. Ohmplus also describes complete solutions for customer use in R&D, production, or field applications, especially for 5G, LEO satellite, and semiconductor testing supply-chain applications, and states that it has Fast Group Testing technology and a platform for AiP, RFIC, and RF front-end IC. The company name is described as evoking Ohm+, Omega, impedance as a factor in electromagnetic-radiation performance, and the symmetry of the omega symbol as a reflection of the symmetry of antenna radiation patterns. In 2021, Ohmplus states that it was founded under the guidance of the Unicorn Program of the Ministry of Science and Technology; in 2022 it received the Outstanding Cooperation Award of the 5G Mobile Broadband Talent Development Program Office and a Silver Medal at the National Invention and Creation Award presented by the Ministry of Economic Affairs. In 2023, the company states that it received investment from the National Development Fund of the Executive Yuan and participated in the Angel Venture Investment Program Results Presentation Conference, and in 2024 it announced attainment of ISO 9001:2015 certification.
Exhibits
The OHMPLUS GT-S Middle Electronic Box (MEB) is a highly integrated signal-expansion module designed specifically for RF front-end-module testing and enables synchronized multi-site testing with minimal instrument configuration to improve testing efficiency and flexibility. Its modular design provides RF, digital, and power interfaces so test configurations can be adapted to the connected instruments, while built-in active components support a frequency range from 500 MHz to 14 GHz. The MEB supports up to +16 dBm maximum continuous input power and delivers up to 16 dB maximum output gain. It provides synchronized testing for as many as 8 ports, and in S-parameter test mode each port can perform Return Loss and Insertion Loss measurements, supporting multi-port RF front-end-module test configurations. When integrated with a Vector Signal Analyzer/Generator (VSA/VSG), the MEB can also perform modulation-signal analysis and measurement, extending the same test platform from S-parameter checks to modulation-related measurements.
