The ARS 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. 2. Similar units are available with analog electronic control of attenuation in the AFF and AEF series and digital control in the AD series. Further varieties are also available in the ARC series including a 75 Ω model for baseband communications systems 3. For special requirements, Merrimac can supply units with special characteristics such as the long shaft version, ARS-1A, which was developed for requirements using a knob. 4. The ARS series can be supplied screened for high reliability to meet specific military and space applications. 28Jun02 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 ARS Series VARIABLE ATTENUATORS, MANUAL DC to 400 MHz / Up to 20 dB Range / Low Insertion Loss / Broadband / PC Mount Package Outline - ARS-1 ARS-1 : Bushing Length 0.40 nom, shaft 0.12 nom.
