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 V.S.W.R. of the appended tables. Furthermore, these attenuators show stable characteristics for environments of varying temperature, humidity, and gases.
