General Notes:
1. The ARC series consists of continuously variable
attenuators utilizing compensated Bridged Tee
Networks to vary signal power. These constant
impedance, very broadband attenuators are designed
to cover frequencies from DC to 400 MHz. Similar units
are available with electronic control of attenuation in the
ARE and ARES series.
2. All Merrimac Attenuators are designed for high
reliability in accordance with applicable paragraphs of
MIL-A-24215 and can be supplied screened to meet
specific military and space applications.
