The HLM-67ABH is a wide DC-67 GHz bandwidth GaAs Schottky diode signal limiter featuring high +27 dBm IP3 and high 1 W power handling. It offers low 1.35 dB typical insertion loss and excellent 19 dB typical return loss from DC through V band and has a typical 1 dB compression point of +8 dBm. Its high power handling makes it ideal for protecting sensitive components and for applications requiring high linearity.
