Attenuators
Analog Devices’ attenuators are available in a broad range of architectures and form factors, giving designers the flexibility to select a part best aligns with their system requirements. The parts are designed for the lowest insertion loss and best accuracy in the specified frequency range. Attenuators are manufactured in GaAs and Silicon (SOI) processes which make them versatile in performance and highly reliable in operation for a wide range of applications in instrumentation, communications, military and aerospace markets.
