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, 15, 20, 26 and

30 dB so that levels can be finely adjusted.

2.SMA Type

AT-103

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

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

the VSWR of the appended tables. Furthermore,

these attenuators show stable characteristics for

environments of varying temperature, humidity, and

gases.
