At QuinStar, we design and manufacture our millimeter-wave receivers for maximum performance. We offer a wide range of components to meet the exacting needs of multiple industries and applications. For example, our product line includes broadband detectors and balanced phase detectors, harmonic mixers and diplexers, spectrum analyzer mixers and diplexers, and upconverters. In addition, we offer balanced mixers, subharmonic mixers, and I-Q mixers.

Most of our receiver products cover the frequency range of 18 – 110 GHz in several waveguide bands. But some products cover the frequency range of 18 – 170 GHz.

As always, if you don’t see what you need here on the website, we are happy to discuss your technical needs and explore solutions.  Contact us at for prompt attention.
