Description
40PCA3060 — Surface-Mount Chip Attenuator (DC–40 GHz, 1 W)
The 40PCA3060 is a surface-mount thin-film chip attenuator that reduces signal power uniformly across frequency, temperature, and power level. Mounting is drop-in or bond-and-wire. It suits amplifier circuits, receivers, up/down converters, phase-matched arrays, and switching networks. Standard terminals are lead-free solder, with tin-lead solder and gold available as finish options.
