Limiting amplifiers from Fairview Microwave span a wide range of frequencies and typically are used to protect microwave receivers by “limiting” excessive input power. Fairview limiting amplifiers accepts a wide range of input power levels, while outputting a limited range of powers with a saturated power output deviation over the frequency range that is independent of the input. Our limiting RF amplifiers provide a wide input dynamic range, high gain levels and typical gain while exhibiting great gain flatness performance for RF, microwave and millimeter wave applications.
Fairview Microwave limiting amplifiers are housed in ruggedized, hermetically sealed enclosures and are designed to withstand harsh environments with a wide temperature operating range. Our coaxial signal limiting amps are unconditionally stable and use built in voltage regulation, bias sequencing and reverse bias protection for additional reliability. The over-voltage protection is installed externally for easy reset on this limiting amp product line and are fully matched internally for 50 Ohm input and output, which eliminates the customers need for any additional external RF components for tuning. Limiting amplifiers with a wide dynamic range commonly are used in electronic warfare and military communications systems.
Most all limiting amplifiers from Fairview Microwave are EAR99.
