QuinStar Technology’s series QLN low noise amplifiers utilize advanced MMICs and discrete devices for state-of-the-art low noise performance in the 18-104 GHz frequency range. These amplifiers operate over up to 4 GHz bandwidth at most frequency ranges of commercial or military interest. Wide range of noise figures and gains are offered over each frequency interval.
The standard amplifier housing offers a wide range and combinations of input and output coaxial connectors or waveguide ports. For 18 to 40 GHz amplifiers, we offer 2.9 mm coaxial connectors, and 2.4 mm for 40-50 GHz and 1.9 mm connector for frequencies beyond. Appropriate waveguide input and/or output ports are offered for the entire range from 18 to 104 GHz. Any valid combination of coaxial and waveguide input and output ports can be supplied, if desired. Integral waveguide isolators are also available for improved input and output matches. A wide range of optional features is available for these amplifiers. Please see page 39 for details of these options. Please see our Product Options section for details of these options.
