Hirose AT-1900 Fixed attenuators - 2w power (sma type) Datasheet

Fixed Attenuators - 2W power (SMA type)
AT-1900 Series
■Features
1.Small Size
Use of alumina for the attenuation element assures
light weight and is cost effective.
2.SMA coupling
Several configurations of SMA plug/jack couplings
are available in stainless steel, assuring durability.
3.High Reliability
Proven and stable performance characteristic under
varying temperature, humidity and adverse
environmental conditions.
