Diamond Chip Attenuator

EMC Technology offers a line of CVD Diamond chip attenuators with extremely high power ratings. With operating frequency of DCto 26.5 GHz, these products are ideal for military and space applicationsbecause of thier high power capability, broad frequency response, small size and light-weight design. The CA0505D are manufactured using all thin film construction. The gold finish on terminals is both wire-bondable and solderable. Standard chip and high reliability tested versions based on Mil-PRF-55342 are available. Select from tape and reel or waffle packaging. These products are lead free, RoHS compliant and S-level approved. Standard available values are 1 through 10, 20, and 30 dB.
