The Agilent 84907L programmable step attenuator offers coaxial measurements to 40 GHz in a compact, rugged design. It offers repeatability of better than 0.03 dB, excellent life greater than 5 million switching cycles per section) and an attenuation range of 0 to 70 dB in 10-dB steps. This latest design evolution sets new standards for size and performance. High attenuation accuracy and low SWR are achieved through the use of miniature thin-film attenuation cards composed of high-stability tantalum nitride film of saphire substrate. Insertion loss is outstanding, with with only 2,4 dB of loss at 40 GHz. The compact size of the unit, 35% smaller than the Agilent 8495/7 (26.5 GHz) family, allows for easy integration into instruments and ATE systems. Frequency range: dc to 40 GHz Insertion loss at 0 dB: 0.6 dB + 0.03 dB/GHz Maximum SWR: 1.25 to 12.4 GHz, 1.5 to 34 GHz, 1.7 to 40 GHz Repeatability life: 0.03 dB maximum 5 million cycles per section Maximum RF input power: 1 W (average), 100 W (peak) Connector type: choice of 2.4 mm female, 2.4 mm male/female Programming connector: 10-pin sockets
