The HLM-40 is a high-power GaAs Schottky diode signal limiter featuring high IP3 and high power handling. It offers low insertion loss and low return loss from DC through Ka band and has a typical 1dB compression point of 15dBm. Its high power handling makes it ideal for protecting sensitive components and for applications requiring high linearity. It is available as a wire bondable die and as a connectorized module.

Linear Regime Electrical Specifications

The electrical specifications apply at TA=+25°C in a 50Ω system. Typical data shown is for the connectorized U-package limiter unless otherwise specified. Linear Specifications valid for input power up to the 0.1dB compression point. See page 5 for P0.1dB graph.

Min and Max limits are guaranteed at TA=+25°C.
