78 fixed attenuators (sma type) at-100, at-200, and at-300 series at-103 at-206 at-310 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. product specifications ratings rated frequency range (note) characteristic impedance maximum input power dc to 18.0 ghz 50 ohms 1 w operating temperature range operating relative humidity -10 ? to +65 ? 95% max. note: the frequency range will differ depending on the model. item standard conditions 1.vibration 2.shock 3.temperature cycle no electrical discontinuity of 1 s or more no damage, cracks, or parts dislocation no damage, cracks, or parts dislocation frequency of 10 to 2000 hz, overall amplitude of 1.52 mm, acceleration of 98 m/s 2 for 2 hours in each of 3 directions acceleration of 490 m/s 2 , sine half-wave waveform, 3 cycles in each of the 3 axis temperature: -55 ? +5 ? to +35 ? +85 ? +5 ? to +35 ? time: 30 15 max. 30 15 max.
