Fixed Attenuators (SMA Type)
AT-100, AT-200, and AT-300 Series
ꢀFeatures
1.Abundant Variations of Attenuators
Attenuation amounts are available in abundant
variations from 0 to 4 dB in 0.5 dB steps, from 4 to
10 dB in 1 dB steps, and in 12, 13, 14, 15, 20, 26
and 30 dB so that levels can be finely adjusted.
2.SMA Type
AT-103(40)
The coupling portions are available in all types of
plug and jack combinations and stainless steel is
used for the external cladding to form a small and
durable structure.
AT-206(40)
3.High Degree of Matching and High Reliability
The design of the attenuation element uses a
distributed constant circuit and metal film resistor. A
high degree of matching is achieved as indicated in
AT-310(40)
the VSWR of the appended tables. Furthermore,
these attenuators show stable characteristics for
environments of varying temperature, humidity, and
gases.
