Questions & Answers / Clarifications

This document provides responses to vendor questions regarding filter dimensions and potential variations for an unspecified opportunity.

• Dimension Consistency: While individual filter types (e.g., LPF, BPF1, BPF2) do not need to be the same size as each other, all filters of the same type must be the same size as each other.
• Engineering Tolerances: Variations within +/- 0.1 inches due to manufacturing tolerances are acceptable, provided the overall size requirement is still met.
• Acceptable Length: A longer, but consistent, length for filters is NOT acceptable. The maximum overall dimension cannot exceed 5x1.25x1.25 inches (excluding connectors).
• Future Needs: The document implies a need for clarification on whether this is a one-time requirement or if future needs are anticipated, which could influence design choices and cost (e.g., NRE fees).

Vendors should ensure their proposed filter designs strictly adhere to the specified maximum dimensions. Any proposed deviations in length, even if consistent, are not acceptable. Further clarification may be needed from the vendor regarding the potential for future orders and the factors influencing dimensional changes.

Amendment / Modification

This amendment extends the response due date for the solicitation.

• Section A - Solicitation/Contract Form
