SMA Plug, 50 Ohm, 27 GHz — Panel Mount with Compression Termination
The TE Connectivity 2081892-1 is an SMA-style plug connector with a male pin contact, designed for RF interconnect applications requiring a 50 Ohm impedance match up to 27 GHz. The stainless steel body with silver housing provides durability and corrosion resistance, while the gold-plated beryllium copper center contact ensures low and stable contact resistance over repeated matings. The panel mount with flange and threaded fastening gives a secure chassis attachment, and the compression termination simplifies cable assembly without soldering — a clean fit for semi-rigid or conformable cable builds.
Key RF and Mechanical Ratings
The 27 GHz max frequency covers L-band through K-band, suitable for microwave links, test equipment, and antenna feeds. The 335 V voltage rating is ample for low-power RF signals; derate as needed for altitude or high-temperature operation.
Panel mount with a flange — the connector bolts to a chassis or bulkhead using the threaded holes in the flange, giving a vibration-resistant installation. The threaded fastening on the mating interface (the standard SMA coupling nut) secures the mate. Shield termination is via screw, which grounds the cable braid to the connector body. Contact termination is compression — the center pin is crimped or compressed onto the cable center conductor, requiring the correct tool for the cable diameter. No soldering needed at the contact, which speeds assembly and reduces heat exposure to the dielectric.
