Marki Microwave surface mount RF/microwave adjustable limiters can be controlled externally via a bias voltage, current, or control signal, allowing users to change the limiting threshold at calibration or in real time. Marki adjustable limiters have a fast recovery time, predictable flat leakage, and optimal insertion loss. These attributes make Marki adjustable limiters ideal for ADC protection, dynamic range management in software-defined radios, and multi-mode communication systems.
