RF amplifier / microwave / limiting / rugged
Pasternack limiting amplifiers cover a wide frequency range are typically used to protect sensitive microwave receivers by “limiting” excessive input power. This wideband limiting amplifiers product line from Pasternack accepts a wide range of input power levels, while responding with a limited range of output powers with a saturated power output deviation over the frequency range, independent of the input. These RF limiting amplifiers demonstrate a wide input dynamic range, high gain levels typical gain while exhibiting excellent gain flatness performance.
Limiting amplifiers are housed in rugged hermetically-sealed packages and are designed to withstand harsh environments with a wide range of operating temperatures. Our limiting amplifiers are unconditionally stable and include built-in voltage regulation, bias sequencing and reverse bias protection for added reliability. Over-voltage protection is installed externally for easy repair and the amplifiers are fully matched internally for 50 Ohm input and output, which eliminates the customers need for any additional sensitive external RF tuning components. Broadband limiting amplifiers with wide dynamic range commonly used in electronic warfare and military communications systems.
