Features
1.Frequency Range from DC to 8 GHz
Although these attenuators are of the surface
mount type, they offer superior high frequency
characteristics from DC to 8 GHz.
2.Abundant Variations of Attenuators
Attenuation amounts are available in 11 types from
0 to 10 dB in 1 dB steps.

q
Make the AT-900 tab height from the housing and the thickness of the microstrip board the same amount.
q
The tabs are attached with high temperature solder (having a melting point of 280
). The soldering temperature to the
microstrip board must be less than this.
