    Introduction Product Overview The 8497K is a 50- ohm, dc to 26.5 GHz, 0 dB to 90 dB (in 10 dB steps), coaxial attenuator with APC 3.5 connectors. The attenuator is made up of four attenuation sections connected in cascade. Each section consists of a precision thin- film attenuator card, a lossless thru- line, and a ganged pair of edge line transmission lines.
