Specifications and Ordering

Our designs are built onsite and upon request. We tailor each order through our sales engineers to better serve your purchase.


QuinStar’s QMB Balanced Mixers down-coverts millimeter-wave signals to broad IF bandwidths with a local oscillator. This mixer is available for RF over 18 – 110 GHz in seven waveguide bands. QMB operates over very broad RF, LO, and IF bandwidths. Additionally, for fixed LO frequency applications, we can provide a very wide IF range if needed. Further, the local oscillator waveguide port may be in either the same waveguide band as the RF waveguide port, or in lower or higher waveguide bands (the two adjacent bands). For IF above 18 GHz, we provide a K connector on the IF port.

For help matching our Balanced Mixer options to your requirements, contact us at or submit an RFQ.
