General Description
The HMC650 / 651 / 652 / 653 / 654 / 655 / 656 / 657
/ 658 are a line of wideband fixed value 50 Ohm mat-
ched attenuator chips which offer relative attenuation
levels of 0, 2, 3, 4, 6, 10, 15 and 20 dB. These passive
though-lines and attenuators are ideal for microstrip,
hybrid, and multi-chip module applications where
extremely flat attenuation, and excellent VSWR vs.
frequency are required.
These wideband attenuators feature low inductance
on-chip vias, and require no additional ground
connections. The HMC650 through HMC658 are
backside metallized with gold, and are suitable for
eutectic or epoxy die attach. Each of the 9 products
can be purchased individually by their respective
part number or in a set of 10 each in the HMC-DK006
Fixed Attenuator Chip Designer’s Kit.
