General Notes:
1. The AU-65A series has been designed for wideband ECM systems and other microwave applications in the 0.3 to 8
GHz frequency band where precise attenuation must be maintained over a wide variety of military and laboratory
environments. Applications include signal and LO power control, automatic level control and impedance matching.
2. The AU-65A series of attenuators use ferrite absorption of microwave energy for long term stability and high reliability.
3. These units can supplied screened to meet specific military and space applications.
