Typical Applications

The HMC650 through HMC658 are ideal for:

• Fiber Optics

• Microwave Radio

• Military & Space Hybrids

• Test & Measurement

• Scientific Instruments

• RF / Microwave Circuit Prototyping

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.
