General Notes:
1. The AUM/AUMP-15A series has been designed for
wideband ECM systems and other microwave
applications in the 1 to 8 GHz frequency band where
precise attenuation must be maintained over a wide
variety of military and laboratory environments.
2. The AUM/AUMP-15A series of attenuators use ferrite
absorption of microwave energy for long term stability
and high reliability. Applications include signal and LO
power control, automatic level control and impedance
matching.
NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted.
3. These units can be supplied screened to meet specific
military and commercial high reliability applications.
2. Dimensions in inches over millimeters.
3. Counterclockwise shaft rotation increases attenuation.
