High Power Fixed Attenuators (Heat sink Mounting Type)
AT-1200 and AT-1300 Series
ꢀFeatures
1.Small Size and Economical
Beryllia is used for the material of the resistance
element to enable the attenuation to be of small
size and low cost.
2.High Power Capacity
Mounting these attenuators to a heat sink permits the
AT-1200 Series to be used at up to 30 W and the AT-
1300 Series to be used at up to 50 W.
3.High Reliability
These attenuators show stable characteristics for
environments of varying temperature, humidity, and
gases.
