The HLM-40 is a high-power GaAs Schottky diode signal limiter that operates from DC to 40 GHz. It can handle up to 20 Watts of peak power (pulsed) and 4 Watts CW power with a flat leakage of 18 dBm at 1 W CW. This device has low insertion loss and low return loss from DC through Ka-band and has a 1dB compression point of 15dBm. Its high power handling makes it ideal for protecting sensitive components and for applications requiring high linearity. The limiter is available as a wire bondable die and as a connectorized module.
