General Notes:
1. The ARS ries consists of continuously variable attenuators utilizing compensated Bridged Tee Networks to vary signal power.The constant impedance, very broadband attenuators are designed to cover frequencies from DC to 400 MHz.

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 ries can be supplied screened for high reliability to meet specific military and space applications.
