About

OSO Semiconductor is an early-stage fabless semiconductor company developing next-generation beamforming RFICs for phased array antenna systems. Founded out of doctoral research at the University of California, Berkeley, OSO has pioneered a novel algorithmic approach to phase shifting that improves efficiency by up to 4x over existing phased array designs, reducing the need for amplification and enabling simpler, smaller, and more power-efficient chips. The company targets satellite communications (SATCOM), 5G infrastructure, and radar sensing markets where high-bandwidth, power-constrained antenna systems are critical. OSO is headquartered in Mountain View, California.
