AFI Adapters

Amphenol RF’s AFI adapters deliver precision-engineered solutions for board-to-board and cable-to-board RF applications where misalignment tolerance, reliability, and ease of use are critical. Offering both in-series and between-series configurations, including transitions to SMA and MCX, the AFI family ensures signal integrity and ease of installation in dense PCB environments.

These adapters utilize a proprietary floating bullet interface that compensates for both axial and radial misalignment—up to 0.038″ radial and 0.050″ axial—delivering consistent performance up to 6 GHz (50 Ω) and 3 GHz (75 Ω) depending on the variant. With robust plated brass bodies and PTFE dielectrics, AFI adapters meet the durability demands of military, aerospace, and broadband systems.

Features and Benefits

• High Misalignment Float – ±0.38 mm radial and ±0.50 mm axial tolerance to simplify blind-mating operations.
• In-Series & Between-Series Flexibility – Includes AFI–AFI and AFI–SMA, AFI–MCX configurations.
• Compact & Robust Design – Low-profile SMD plug and jack bodies optimized for dense PCB layouts.
• Industry-Standard Impedance – Available in 50 Ω versions up to 6 GHz; AFI‑75 Ø supports 75 Ω systems to 3 GHz.
• Crash-Proof & Blind-Mate Capable – Shrouded bullet interface protects contacts and simplifies mating.

Applications

• Military & Aerospace – Ideal for blind-mate modules with vibration and alignment tolerance needs.
• Broadband Telecommunications – Supports board-stack flexibility and reliability in broadband routers.
• Cable Modem & Networking Equipment – Perfect for compact PCB-to-board and board-to-cable links.
