RoHS Compliant Waveguide Manufacturer

We make custom waveguides and assemblies. Fast.

QuinStar is the leading waveguide manufacturer at millimeter-wave frequency. Our products cover 18 – 220 GHz in ten frequency bands. The bands are K-band, Ka-band, Q-band, U-band, V-band, E-band, W-band, F-band, D-band, and G-band. In addition, we stock a large inventory of waveguide components. But if we don’t have what you need in stock, we can make it. Because our waveguide shop is on site, we can quickly make custom solutions based on your drawings. The tubing can be coin silver, copper, or brass with brass flanges. Please contact sales@quinstar.com for information on sub assemblies and assemblies.

These products comply with RoHS. Additionally, we can meet MIL-DTL-85/3 if required. To learn more, visit these product pages:

While our shop can work from a simple hand sketch, a 2D CAD drawing reduces our lead time. Furthermore, a 3D CAD model file ensures our fastest lead time.

Our custom ability is top notch.

In addition to standard products, we can make both custom waveguide assemblies and sub-assemblies quickly. Lead time depends on materials and specifications. Contact us directly to learn more.

In fact, QuinStar specializes in custom work. We can convert your solid model 2D drawing into reality in a very short time. Custom assemblies often involve complex bends, twists, and other special mechanical features. Our advanced video inspection system will ensure your complex requirements are met. We are happy to discuss your requirements at any time in the development lifecycle—before or after your design is complete.

Each custom assembly is precisely made to meet your requirements. Because we are a full-service engineering company, QuinStar can offer design services if needed. Based on your requirements, we use the most suitable material, flanges, and finish.
