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.
