Procurement Notes

Verify the specific datasheet version provided by Pasternack Enterprises, Inc., as technical specifications may vary between revisions. Confirm that the TTL control logic levels match your system requirements before integration. Ensure the 2.92mm connector compatibility with existing fixture interfaces. Request official documentation directly from the manufacturer or authorized distributors to validate current production status and exact electrical parameters for your specific batch.

Selection Notes

Select this model when a wide bandwidth extending to 43.5 GHz is required alongside digital programmability. The absorptive architecture offers advantages over reflective types in mismatched load environments. Consider the 2.92mm interface if high-frequency precision is critical compared to standard SMA or V-band options. Evaluate the TTL control voltage compatibility with your microcontroller or FPGA outputs to ensure seamless integration without additional level-shifting circuitry.

Part Context

This component belongs to Pasternack's series of RF attenuators, specifically focusing on digitally controlled solutions. It complements fixed attenuator models like the PE7015-40 by offering variable attenuation capabilities. The product line emphasizes modular designs with field-replaceable connectors to simplify maintenance and extend operational lifespan in demanding laboratory and industrial settings.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users should consult Pasternack technical support for direct equivalents or cross-reference options based on specific frequency and attenuation requirements.

FAQ

What type of attenuation technology does the PE70A5015 use?

It utilizes absorptive technology, which dissipates reflected power rather than reflecting it back to the source.

How is the attenuation value controlled?

The attenuation is digitally controlled using a TTL interface, allowing for programmable adjustment of the signal loss.
