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.

3. These units can be supplied screened to meet specific

military and commercial high reliability applications.
