Typical Performance

GENERAL SPECIFICATIONS

Resetability (Granularity): 0.2 dB

Impedance:

50 W nom.

Operating Temperature:

-- 55° to +85°C

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

electroniccontrolofattenuationintheAFFand

AEF series and digital control in the AD series.

Further varieties are also available in the ARC

series including a 75 W 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.
