Data Sheet SHF ATT67 A
SHF Communication Technologies AGDescription
The SHF ATT67 A is a compact, high-performance, RoHS compliant attenuator with a bandwidth exceeding
67 GHz1 and a very flat frequency response.
Its small footprint makes it particularly suitable for differential applications, where signals entering or
leaving close-spaced connectors need to be attenuated simultaneously. Furthermore, dedicated mounting
holes on the back side allow secure installation on a mounting plate for stable system integration.
A broad range of attenuation values is available within the same series (ATT67 A | xx dB).

Features• Small and lightweight• Flat frequency response• Low reflection

Configurations• VFVM: 1.85 mm female to 1.85 mm male
• Other configurations on request

Product Code Example•SHF ATT67

A| 20 dB|VFVM

1Due to the intrinsic geometry of V connectors, energy could couple to high-order modes for frequencies above 67
GHz.
