AMC4 Adapters
Ultra-compact snap-on RF adapters providing seamless transitions between AMC4 and standard RF interfaces, tailored for space-constrained wireless systems.
Overview
Amphenol RF’s AMC4 Adapters bridge ultra-miniaturized RF board-level connections to a wider range of interfaces such as SMA, RP‑SMA, MMCX, MCX, and RP‑TNC. Ideal for handheld devices, IoT modules, and embedded systems, AMC4 adapters enable flexible in-series and between-series pairings while preserving signal integrity up to 6 GHz.
Built around Amphenol RF’s fourth-generation micro-coaxial AMC4 connector—featuring a mere 2 mm × 2 mm footprint and only 0.6 mm mated height—these adapters are designed for dense PCB layouts and tight enclosures. With robust metal bodies, PTFE insulators, and snap-on coupling, AMC4 adapters deliver reliable performance at high frequencies, handheld portability, and lab-grade durability.
Features and Benefits
- Snap-On Simplicity – Fast, tool-free connections with reliable engagement suited for tight spaces.
- Ultra-Miniature Design – Smallest form factor in the portfolio (0.6 mm height, 2 mm footprint) to optimize PCB space.
- Multi-Interface Adaptability – Offers transitions from AMC4 to SMA, RP‑SMA, MMCX, MCX, and RP‑TNC (both straight bulkhead and in-series).
- Compact Board-to-Cable Integration – Enables seamless small-device connectivity with board-level hosting and cable attachment.
- 50 Ω Performance Up to 6 GHz – Precision-matched for high-frequency signal integrity.
Applications
- IoT, Wearables & Handheld Devices – Board-to-cable connectivity in ultra-compact systems requiring robust RF performance.
- Embedded Wireless Modules – AMC4 to SMA/RP-SMA adapters support test ports and external antenna access.
- Test & Measurement – Bulkhead adapters serve as panel-mounted connector savers for handheld RF instruments.
- RF Sensor Networks – Compact and reliable RF transitions for distributed sensing platforms.
- Consumer Electronics & GPS – Support for Bluetooth®, GPS, and other RF protocols in miniature form factors.
