The Quinstar QLN-2810PN is a low-noise amplifier (LNA) engineered for millimeter-wave applications across the 18–104 GHz spectrum. Designated for operation around 28 GHz, this device leverages advanced MMICs and discrete components to deliver exceptional noise performance in demanding RF environments. The amplifier supports bandwidths up to 4 GHz and operates reliably across commercial and military platforms. QuinStar configures the QLN-2810PN with selectable gain and noise figure options tailored to specific frequency sub-ranges. Integral waveguide isolators are available to optimize input and output matching. The unit accommodates multiple connector architectures—coaxial ports (2.9 mm for 18–40 GHz, 2.4 mm for 40–50 GHz, 1.9 mm above 50 GHz) or waveguide ports spanning the full 18–104 GHz range—with custom hybrid configurations available upon specification.
