(56 g) -- 55° to +85°C 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. 28Jun02 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 ARC Series VARIABLE ATTENUATORS, MANUAL & 75 / BNC & SMA DC to 400 MHz / 0 to 20 dB Range / Broadband / Panel Mountable / 50 ARC-1 (& ARC-3) Package Outline NOTES: 1.
