QPL 军用认证
Amphenol RF offers QPL military-approved RF connectors and adapters for aerospace and defense applications requiring reliable RF performance and compliance with applicable U.S. military specifications. Available configurations include BNC, TNC, N-Type, SMA and RF adapters, providing qualified interconnect options for demanding military and aerospace systems.
MILITARY-QUALIFIED RF INTERCONNECT SOLUTIONS
Qualified RF Connectivity for Mission-Critical Systems
Qualified Products List (QPL) approval identifies specific RF connector and adapter configurations and manufacturers that have met the qualification requirements of applicable U.S. military performance specifications. These requirements address electrical performance, mechanical durability and environmental conditions.
Unlike connectors described simply as military-grade or ruggedized, QPL-qualified products have documented qualification tied to specific military part numbers and approved manufacturers. Amphenol RF provides part-number cross-references and technical documentation to help engineers verify qualified configurations and select appropriate RF interconnect solutions.

Military RF Specifications and Connector Qualification Requirements
Military RF specifications establish requirements for coaxial connectors, mating interfaces and RF cables. Understanding the role of each standard helps engineers evaluate electrical performance, mechanical compatibility and qualification requirements when selecting RF interconnect solutions for aerospace and defense applications.
| Specification | Primary Focus | Engineering & Selection Guidance |
|---|---|---|
| MIL-PRF-39012 |
RF Coaxial Connectors
Performance specification |
Establishes performance and testing requirements for applicable RF coaxial connector configurations. Verify the exact military part number, specification sheet, qualified manufacturer and current qualification status. |
| MIL-STD-348 |
RF Connector Interfaces
Interface standard |
Specifies dimensional requirements for applicable RF connector mating interfaces. Confirm interface geometry and mechanical compatibility. Compliance with interface dimensions alone does not establish QPL approval. |
| MIL-DTL-17 |
RF Coaxial Cables
Detail specification |
Defines construction, electrical and performance requirements for flexible and semirigid RF coaxial cables. Evaluate impedance, cable construction, applicable environmental requirements and compatibility with the selected connector and cable assembly. |
Qualification Note: Compliance with a military specification does not automatically establish QPL approval for every product. When qualification is required, verify the exact military part designation, applicable specification and approved manufacturer against current qualification records.

Frequently Asked Questions About QPL RF Connectors
Find answers to common questions about military-qualified RF connectors, MIL-PRF specifications, qualification verification and military part-number identification.
What does QPL mean for RF connectors?
QPL stands for Qualified Products List. It identifies products qualified under applicable government specifications. Qualification applies to specific approved products and manufacturers.
Are all military-grade connectors QPL approved?
No. A rugged or military-grade connector is not automatically QPL qualified. Verify qualification for the exact product designation and approved manufacturer.
How do M39012 and Amphenol RF part numbers differ?
An M39012 designation identifies a military specification configuration. An Amphenol RF part number identifies a corresponding manufacturer product. Use the QPL/UG cross-reference to identify available matches.
What is MIL-PRF-39012?
MIL-PRF-39012 is a military performance specification covering RF coaxial connectors. It defines applicable performance, testing and qualification requirements.
How do I verify QPL qualification?
Review current records in the Defense Logistics Agency's Qualified Products Database. Confirm the applicable specification, exact military part designation and qualified manufacturer.
Can a commercial connector replace a QPL connector?
Only when the applicable program requirements and approval process permit substitution. Similar mating interfaces do not establish qualification equivalence.
