General Notes:
1. The AU/AUP-25 series of microwave attenuators
has been designed for wideband ECM systems and
other applications in the 1 to 19 GHz frequency band
where precise attenuation must be maintained over
a wide variety of military and laboratory
environments.
2. Applications include signal and LO power control,
automatic level control and impedance matching.
3. The AU/AUP-25 series uses ferrite absorption of
microwave energy for stability and high reliability.
They can be supplied screened to meet specific
military and commercial high reliability applications.
NOTES:
1. Tolerance on 3 place decimals
±
.020(.51) except as noted.
2. Dimensions in inches over millimeters.
3. Clockwise micrometer rotation increases attenuation.
