The ATN15-0040CH is part of a family of precision GaAs MMIC fixed attenuators. The ATN15-0040CH provides a nominal 15dB attenuation over a DC-40GHz operating range. These attenuators are an ideal solution for attenuating a signal and they can be used in a wide range of applications. They are ideal for test equipment’s protection and signal overload prevention in various RF systems. A 50-ohm match is maintained over the entire operating frequency range.
