General Notes:
1. The AU-26 series of Ferrite Attenuators has been
designed for wideband ECM, EW and radar
systems and other applications in the 1 to 11 GHz
frequency band where precise attenuation must be
maintained over a wide variety of military laboratory
environments. Applications include signal and LO
power control, automatic level control and
impedance matching.

2. The AU-26 series of attenuators uses ferrite
absorption of microwave energy for long term
stability and high reliability.
3. These units can be supplied screened to meet
military and commercial high reliability applications.
