mmTron is a Redwood City, California semiconductor company that designs high-performance millimeter-wave integrated circuits (MMICs). Founded in 2020 by Seyed Tabatabaei and Mona Molaasgari, the company builds power amplifiers, low noise amplifiers, front-end modules, mixers, switches and wideband distributed amplifiers using GaAs, GaN, InP, SiGe and RFSOI process technologies. Its chips target the linearity, bandwidth and power-efficiency demands of satellite communications, 5G/6G wireless, aerospace and defense radar, and RF instrumentation up to 180 GHz. In April 2026 mmTron closed a $45M Series A led by Maverick Silicon.
