AMMC Adapters

Amphenol RF’s AMMC adapters bridge ultra-miniature board-mounted RF interfaces to standard cable connectors in applications that demand small footprints and reliable performance. Featuring in-series (AMMC–AMMC) and between-series transitions like AMMC–SMA, the product family ensures seamless connectivity in IoT devices, test modules, and embedded systems.

These adapters utilize the same AMMC (Amphenol Micro‑Miniature Coaxial) 2 mm × 2 mm footprint and 1.4 mm mated height as the connectors—enabling blind-mate or panel-friendly configurations in high-density designs. With precision-engineered PTFE insulators, plated bodies, and snap-on coupling, AMMC adapters support up to 6 GHz with stable electrical performance in rugged environments.

Features and Benefits

• Ultra-compact size – Minimizes PCB space with a footprint of just 2 mm × 2 mm and a 1.4 mm mated height.
• Snap-on reliability – Tool-free engagement with consistent mating for compact, automated assembly.
• Flexible configurations – Supports AMMC–AMMC in-series and AMMC–SMA between-series transitions.
• High frequency performance – Designed for broadband RF use up to 6 GHz.
• Dense RF layout compatibility – Ideal for board-to-board or board-to-cable solutions in tightly packed systems.

Applications

• IoT & Wearable Devices – Compact AMMC–SMA adapters enable external antenna connections in miniature electronics.
• Embedded Wireless Modules – Internal board-to-board AMMC transitions support GPS, BLE, and other RF paths.
• Test & Measurement Equipment – Snap-on bulkhead adapters serve as connector savers for test fixtures and mini-instruments.
• RF Sensor and Instrument Modules – AMMC interfaces allow for modular board stacking with high-density signal routing.
• Consumer Electronics & Micro-Antenna Systems – Rock-solid RF connections in miniature multi-board assemblies.
