QUINSTAR TECHNOLOGY, INCORPORATED

Quinstar Technology, Incorporated specializes in the design and manufacturing of high-frequency RF and microwave subsystems for defense and space applications. Their core capabilities center on developing low-noise amplifiers, solid-state power amplifiers, transceivers, and variable attenuators operating in Ka-band, V-band, and F-band frequencies. The company excels in precision instrumentation for signal testing, including cryogenic circulators, and delivers engineered solutions for radar, communications, and satellite systems. Their technical expertise spans solid-state microwave component design, high-linearity amplifier architectures, and thermal management for extreme environments, with a demonstrated focus on SBIR-funded R&D for next-generation space and airborne platforms. Quinstar’s differentiation lies in its ability to transition complex RF prototypes into ruggedized, mission-critical hardware compliant with stringent aerospace and defense performance standards. The contractor maintains a strong relationship with the Department of Defense, providing mission-critical RF components for electronic warfare, surveillance, and secure communications systems. They also support the National Aeronautics and Space Administration with advanced microwave amplifier technologies for deep-space communication and Earth observation payloads. Their work with these agencies reflects a pattern of sustained collaboration on high-reliability, frequency-agile subsystems for next-generation platforms. Quinstar’s primary industry focus is in RF and microwave equipment manufacturing, particularly under NAICS 334511 and 334515, where they deliver specialized instrumentation for signal measurement and aeronautical system integration. Their work in research and development (NAICS 541715) underscores a strategic positioning as a niche innovator in millimeter-wave technologies for government aerospace and defense markets. As a small business structured as a 2L entity based in Torrance, California, Quinstar operates without federal certifications but maintains a focused presence in the defense and space supply chain, serving as a trusted provider of high-performance RF subsystems for mission-critical applications.
