Fixed Attenuators (SMA Type) (DC to 18.0 GHz) AT-100, AT-200, and AT-300 Series AT-103 AT-206 AT-310 Attenuation amounts are available in abundant variations from 0 to 4 dB in 0.5 cB steps, from 4 to 10 dB in 1 dB steps, and in 12, 13, 15, and 20 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. Rated frequency range (NOTE) DG to 18.0 GHz Characteristic impedance 50a Maximum usable power 1W Rating Operating temperature range -10C to +60C Operating relative humidity 95% ar less NOTE: The frequency range will differ depending on the model. tem Standard Conditions 1.Vibration resistance | No electrical disconnections of 1 1s or greater No damage, cracks, or parts looseness Frequency of 10 to 2000 Hz, overall amplitude of 1.52 mm, 98 m/s acceleration, in 3 axial directions, 2 hours each 2.
