The SMA Receptacle with Specialized Panel Shapes is an RF connector variant designed to be mounted on panels with non-standard or custom cutouts. It maintains the core SMA features—such as a threaded coupling mechanism and consistent 50 Ω impedance—while offering customized flange or body geometries to suit specific mechanical design requirements. These connectors ensure stable high-frequency performance, typically up to 18 GHz, and are used in applications where standard panel-mount connectors cannot fit due to space constraints, unique enclosure designs, or integrated component layouts, such as in aerospace, defense, and compact communication systems.
