General Notes:
1. 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.
