AMC4 Connectors
Ultra-compact micro-coax connectors engineered for next-gen RF applications up to 6 GHz+
Overview
Amphenol RF’s AMC4 connector series offers a high-performance, space-efficient micro-coax solution designed for demanding RF and microwave applications. These cable-mount connectors support up to 6 GHz and, depending on the configuration, can meet higher-frequency requirements suitable for emerging Wi-Fi 7 designs. Engineered with precision metal construction, AMC4 connectors maintain stable impedance and low VSWR in even the tightest PCB layouts.
Specifically made for micro-coax cable assemblies, AMC4 connectors are available in vertical and right-angle variants, streamlining integration in handheld instruments, IoT devices, and compact wireless modules. Their robust board interface and durable contacts ensure reliable signal integrity in applications where both mechanical stability and electrical performance are essential.
