Manufacturing of a K Band Crygenically Cooled Low Noise Amplifier

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.
