The 50 ohm assemblies are available in a variety of plug and jack configurations that terminate to ultraminiature AMC and AMC4 connectors. The robust mechanical MCX design makes devices suitable for rugged applications with space constraints such as drones and consumer devices. The smaller MMCX to AMC or AMC4 cable assemblies are used to make connections between pcbs and modules in tight spaces for IoT infrastructure. Connectors are manufactured with brass bodies while the AMC and AMC4 connectors, featuring a gold or silver plated phosphor bronze body.
