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 QAI Instrumentation Amplifiers are fully packaged, high-performance amplifiers.  Standard products include power amplifiers, general-purpose amplifiers, and broadband driver amplifiers in frequency ranges covering 2 – 110 GHz. We package these amplifiers in rugged equipment enclosures with all power supplies and control circuits included for AC power operation. Further, we can build models that operate on DC power supplies (12 or 24 V). The enclosure can be standard rack-mountable or custom  depending on your requirements.

QAI includes displays, indicators, controls, and cooling arrangements for ease of operation with high reliability. Additionally, we offer a wide range of optional features for these amplifiers.   In sum, we can configure and produce custom amplifiers to meet virtually any performance and operational requirements.


These amplifiers work well for test and measurement use, laboratory use, and TWT replacement, as well as for dedicated instrumentation sources.
