Standard Digital

Advanced Control Components’ line of switched-bit PIN diode digital attenuators offers precision, reliability, and repeatability for the most demanding applications. The AT series digital attenuators are available in convenient binary 4-, 5-, and 6-bit configurations with 0.5dB resolution and up to 63dB total attenuation. The attenuators require only a single +5 V DC power supply and feature TLL compatible control logic. All switches incorporate DC blocks at the RF poerts. Standard screened devices incorporate epoxy sealed lidsand undergo a stringent yet cost effective screening cycle. The attenuators are also available with hermetic seal and high-rel screening for mil and space applications.
Applications
EW Systems, Communications Systems, Automatic Gain Control, Test Equipment, Electronic Simulators, Levelling Circuits
