The DLM-10SM is a tunable, dual channel GaAs Schottky diode signal limiter featuring 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 available in a lead-free, RoHS compliant QFN surface mount package and is compatible with standard leaded and lead-free PCB reflow soldering processes. The DLM-10SM is a superior alternative to discrete diode limiting options.

Electrical Specifications – Specifications guaranteed from -55 to +100°C, measured in a 50Ω system.
