Lange couplers, used as power combiners in high-power amplifiers, have a substantial effect on system-level efficiency. Nuvotronics has developed cost competitive Lange couplers with improved performance over current processes. An AS9100D certified manufacturer of mmWave solutions and components, our proprietary photolithography wafer-based additive manufacturing process produces the industry’s smallest, lightest, highest performing solutions. Shipborne high-power transmit amplifiers are replacing vacuum tube technology with solid-state power amplifiers (SSPAs) where hundreds of modules with Lange couplers are combined. Radar transmit/receive (T/R) modules employ Lange couplers in the transmit output stage. Our patented process makes Lange couplers that are exceptionally small, light, capable of handling high power, and extremely repeatable mechanically and electrically and could become a key component in future Navy radar and electronic warfare (EW) systems.
