Anritsu 5400-71N75 0.001 GHZ to 3 GHz Detector

The Anritsu 5400-71N75 is a 75 Ohm RF detector engineered for precision power measurements from 0.001 GHz to 3 GHz. Built around zero-biased Schottky diodes, this detector integrates with scalar network analyzers and measurement systems to quantify coaxial transmission loss, gain, and absolute power across the microwave band. The unit accepts a Type N Male connector and delivers measurement accuracy across a -55 dBm to +16 dBm dynamic range with controlled frequency response and return loss characteristics.
