These constant impedance, very b roadband attenuators are designed to cover frequencies from DC to 400 MHz. 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 communication systems. For special

requirements, Merrimac can supply units with special characteristics s uch as the long shaft version, ARS - 1A, which was developed for requirements using a knob. The ARS series can be supplied screened for high reliability to meet specific military and space applications.
