Custom Low Noise Amplifiers

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 in³ (Non-cooled), 50 to 100 in³ (Thermal Electric Cooled), 13824 n³ (Cryogenic Cooled), 2000 in³ (Controller), and 665 in³ (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.
