Ruggedized design operates up to high input powers often seen at Receiver inputs
eliminating the need for an external limiter.
Low, small signal operating current of 57 mA nominal maintains junction temperatures
typically below 100°C at 85°C ground lead temperature.
Max Input Power, +27 dBm
High Reliability
