QuinStar

QuinStar

QuinStar Technology is a manufacturer of millimeter-wave and microwave components and test instruments, covering frequencies from microwave through the millimeter-wave spectrum up to 110 GHz and beyond. The company produces a broad range of passive and active RF components including attenuators, noise sources, amplifiers, mixers, detectors, and waveguide hardware used in test systems and research applications.

QuinStar specializes in waveguide and coaxial millimeter-wave hardware designed for precision test and measurement in laboratory and system integration environments. Their calibrated noise sources and attenuators are widely referenced for characterization of receivers, radiometers, and radar systems operating at millimeter-wave frequencies.

Key Product Lines

• Millimeter-Wave Attenuators — fixed and variable attenuators for signal level control in waveguide and coaxial configurations
• Noise Sources — calibrated broadband noise sources for receiver and radiometer noise figure characterization
• Amplifiers — low-noise and power amplifiers covering millimeter-wave frequency bands
• Mixers and Detectors — broadband waveguide mixers and power detectors for millimeter-wave test setups

Industries Served

QuinStar components are used in radar and electronic warfare systems, satellite communications, radio astronomy, atmospheric sensing, automotive radar at 77/79 GHz, and 5G millimeter-wave R&D. Their hardware is found in defense and government research laboratories, university research facilities, and commercial wireless test environments.
