QuinStar Technology’s series QLW low noise amplifiers utilize advanced MMICs and discrete devices for state-of-the-art noise performance in the 2-110 GHz frequency range. The majority of these amplifiers offer greater than a standard waveguide bandwidth, and use appropriate coaxial or waveguide interfaces. The standard amplifier housing offers a wide range and combinations of input and output coaxial connectors or waveguide ports. For standard products in 18 to 40 GHz range, we offer 2.9 mm coaxial connectors, and2.4 mm for 40-50 GHz and 1.9 mm connector for frequencies beyond. Any valid combination of coaxial and waveguide input and output ports can be supplied, if desired. These low noise amplifiers are useful in EW systems, test equipment, and instrumentation systems where low system noise figure is very important. A wide range of optional features is available for these amplifiers. Please see our Product Options section for details of these options.
