Satellink is an accomplished supplier of state-of-the-art low noise linear amplifiers found in cutting edge applications. We designed and manufactured the UHF diplexer LNA for a customer in the unmanned aerial vehicle (UAV) industry, where lightweight construction, economically-sized packaging, and precision performance are critical. In addition to engineering, we sourced all the required components, assembled the devices, and applied a protective chromate conversion coating. Quality assurance protocols, conducted in accordance with MIL-STD-810, included functional testing as well as dimensional inspections and verification. Featuring an EMI-shielding aluminum enclosure, this LNA provides transmit-receive functionality from a 5.37" in height, 4.50" in width, and 1.12" in depth package. Weighing only 2 lbs., it operates in the 248 to 270 MHz minimum frequency range and offers a low noise figure of 2.0 dB max. We designed it to withstand temperatures from -55°C to 71°C, 100% humidity conditions, and pressures at altitude of up to 70, 000’. It was designed to provide 230, 000 hours of stable, reliable operation.
Satellink has a long history of meeting the stringent demands of military and government communication applications. We employed our decades of technical expertise for the design and manufacture of this multi-channel telemetry frequency converter for the satellite launch, tracking, and monitoring industry. We engineered this frequency converter to provide a robust, high-stability receiver solution for remote terminal data collection. Our highly disciplined engineering team established and refined the design to ensure it was qualified to perform according to customer specifications. We sourced the components and performed all assembly, silk screening, and painting operations inside our Texas facility. Extensive functionality testing verified the device was in conformance with MIL-STD-461 requirements for the control of electromagnetic interference. Designed to operate over 4 frequency bands, it features a low noise figure of 10.5 dB max, gain of 15 dB ± 1.0 dB, and 50 ohm nominal inputoutput impedance. Measuring 15.5" in length, 15.0" in width, and 6" in height, it was constructed to withstand temperatures from 0°C to 50°C.
Satellink has the deep, multi-disciplined engineering knowledge required to manufacture amplifiers that can be cycled down to cryogenic temperatures without causing any mechanical or electrical degradation. We manufactured this cryogenically cooled K band amplifier to provide a very low noise solution for the video, telemetry, and communications industry. Designed for 24-hr operation, this device features a 19" rack-mount configuration with built in test wavelength switch monitors, front panel controls, digital status indicators, and LED alarm. Along with an air-cooled compressor, it offers WR51 RF input and 3.5 mm SMA RF output connectors. Operating in the 17.7 to 21.30 GHz frequency range, it features ultra-low noise temperature of 55K maximum @ +23°C. We engineered and built this complex component from start to finish over a 6 month time period. Its robust feature set and ultra‐low noise operation were critical for maintaining reliable communication links.

At Satellink, we have built our reputation with high quality, state-of-the-art amplifiers and electronics. We were recently contacted by a customer in the remote satellite downlink telemetry industry to manufacture a phase matched and tracking Ku Band low noise amplifier. We engineered, designed, component sourced, and assembled this product, which was fully operational in the Ku Frequency Band when completed. The amplifier was phase matched to ± 10°, phase tracked within ± 10°, and packaged in a weather resistant and EMI sealed enclosure. The amplifier had electrical specifications that included a frequency range of 13.40 to 14.05 GHz, an RF Gain ranging from 50 dB minimum to 52 dB maximum, and a noise temperature maximum of 65°K. The final product was 9.07” in length, 2.60” in width, and 3.70” high, and weighed 60 ounces. It featured a widely variable operating temperature range, from 55°C all the way down to -25°C. Special attention was paid to quality during manufacturing, including functionality tests, visual inspections, and environmental screening. The project was completed in 155 calendar days, and delivered to our client in Garland, TX.
