Delta MMCX and MC-Card switching receptacles automatically switch from an internal circuit and an external circuit when mated. They are ideal for use in applications such as portable computers operating in wireless networks, allowing for automatic switching between the internal antenna and a higher-gain external antenna. Their frequency range is DC–3 GHz when switched to internal circuits and DC–8.5 GHz when switched to external circuits.
These receptacles are designed for card-edge surface mounting, and are available either with individual or tape-and-reel packaging. These receptacles are compatible with all MC-Card and MMCX plugs.
