The DLM-10SM from Marki Microwave is a tunable limiter that operates from DC to 10 GHz. This dual channel GaAs Schottky diode signal limiter has excellent IP3, insertion loss, and return loss. The limiting level is adjustable with an off-chip bias network, and the two channels can be used for differential or single-ended signals. The DLM-10SM is a superior alternative to discrete diode limiting options. It is available in a lead-free, RoHS compliant QFN surface mount package.
