SAT-3DC-3A+
CASE STYLE: FF99
Product Overview
SAT-3DC-3A+ is a DC Passing fixed attenuator in 100 MHz to 500 MHz frequency range with excellent flatness
of attenuation. These units support testing applications. Precise performance, excellent VSWR (1.1:1 typ.) and
rugged construction make these models ideal solutions for systems requiring precise attenuation across very wide
frequency range.
Key Features
Feature
Excellent VSWR, 1.10 typ
Advantages
Well-matched for 50Ω systems; reduces effects of phase variation
Flat attenuation
Accurate performance within ±0.8 dB over the full frequency range.
Rugged construction
Excellent durability for a long lifetime of use.
