Ordering Information
Features
AT: Indicates a fixed attenuator
Indicates the Series Name (Coupling Portion)
1: SMA plug - jack
2: SMA plug - plug
3: SMA jack - jack
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.
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.
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.
Operating temperature range
