Amplifier Ic

For over 30 years, Satellink has been providing precision microwave products to customers across a spectrum of industries, with airborne, shipboard, and ground based applications. We offer custom design and manufacturing of high performance low noise amplifiers, with available amplifier types including non-cooled ambient amplifiers, thermal electric cooled amplifiers, and cryogenic cooled amplifiers. Wave guide and coaxial interface options are offered, as well as choice of connectors. Operational functions include low noise pre-amplification of received signals, and active gain over temperature.
Our precision low range amplifiers cover a frequency range of RF (300 MHz) to KA (30GHz), gain levels of 20 to 70 dB, and a noise figure of 0.40 to 1.50 dB. The Voltage standing wave ratio (VSWR) is 1.25:1. Pre-selection and image rejection filters are utilized for optimized performance. Available sizes vary with model: 2 to 10 in (Non-cooled), 50 to 100 in (Thermal Electric Cooled), 13824 n (Cryogenic Cooled), 2000 in (Controller), and 665 in (Compressor). Our designs produce units that amplify weak signals without unintentionally radiating frequencies that interfere with other equipment. All production takes place in our ISO 9001:2008 certified facility, featuring 3 separate lab areas for certain frequency work.

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 @ +23C.
We engineered and built this complex component from start to finish over a 6 month time period. Its robust feature set and ultralow noise operation were critical for maintaining reliable communication links.

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 90K max and high gain of 45 dB nominal. Features include environmental monitoring, alarmstatus signals, and an Ethernet remote interface. Our high quality design and construction supports a reliability factor of 50, 000 hours or better.

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 65K. 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 55C all the way down to -25C. 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.
