General Notes:
1. The AUM/AUMP-25A series has been designed for wideband ECM systems
and other microwave applications in the 0.5 to 12 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 AUM/AUMP-25A series of attenuators use ferrite absorption of
microwave energy for long term stability and high reliability. They meet
applicable paragraphs of MIL-A-24215 and can be supplied screened to meet
specific military and commercial high reliability applications.
