Manufacturing of a Thermoelectrically Cooled K Band Low Noise Amplifier

Here at Satellink, our range of expertise for providing insightfully designed and built low noise amplifier solutions has made us a leading provider to the satellite antenna systems industry. We manufactured the K Band low noise amplifier shown here for a remote ground antenna terminal application, and it required strict adherence to multiple military specifications.

Thermoelectrically cooled to dissipate heat and keep temperatures within design limits to maintain stable functioning, this device features a rack-mount aluminum enclosure with dimensions of 8.75" in length, 7.00" in width, and 6.00" in height. Constructed to within a ± 0.010" tolerance requirement, it also features a MIL-DTL-5541 conversion coating and was finished with a low VOC polyurethane topcoat specifically designed to protect military ground support equipment.

Operating in the 17.75 to 21.25 GHz frequency range, this LNA exhibits low noise temperature of 90°K max and high gain of 45 dB nominal. Features include environmental monitoring, alarm/status signals, and an Ethernet remote interface. Our high quality design and construction supports a reliability factor of 50,000 hours or better.

Military standards are known to be the toughest in the industry and our depth and breadth of experience has made us a top supplier to this market. Additional features of this device are outlined in the table below. If you would like more information or want to discuss the details of your next project, contact us today.
