Hirose AT-901 Stripline mounting fixed attenuators (dc to 8 ghz) Datasheet

Stripline Mounting Fixed Attenuators (DC to 8 GHz)
AT-900 Series
■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.

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