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
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.
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.
