SMAGH Coaxial Attenuator, 2 Watts

SMAGH series coaxial fixed attenuator covers frequency from DC to 26.5GHz and features low VSWR, flatness attenuation value and excellent capacity in anti-pulse and anti-burnout etc..

Coaxial fixed attenuators are used in absorbing energy of transmission line, expanding power range and controlling power level, they are also used in accurately measuring power or spectrum of RF microwave transmitters accompany with small power meter, comprehensive tester or spectrum analyzer.

Key Features

Wide frequency range up to 26.5 GHz

2 W average power and 0.5 kW peak power

Low VSWR and flatness attenuation

50 ohm nominal impedance
