High Power Fixed Attenuators (Radiator built-in)
AT-1000 and AT-1100 Series
s
Features
1.Small Size and Economical
Beryllia is used for the material of the resistance
element to enable the termination to be of small
size and low cost.
2.Connectors Used
In the coupling portion, the AT-1000 Series has an
SMA type plug-jack and the AT-1100 Series has an
N type plug-jack.
3.High Reliability
These attenuators show stable characteristics for
environments of varying temperature, humidity, and
gases.
