General Notes:
1. The AU-46 series has been
designed for wideband ECM
systems and other microwave
applications in the 0.5 GHz to 8.0
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-46 series of attenuators
use ferrite absorption of
microwave energy for long term
stability and high reliability. They
can be supplied screened to meet
specific military and commercial
high reliability applications.
