SMA Connectors General Description 1 Delta SMA connectors are subminiature, precision, 50 impedance connectors with 4 -36 threaded coupling. They are best suited for use with high-frequency semi-rigid cables in demanding applications up to 18 GHz, or miniature exible cables up to 12.4 GHz. Our extensive line of SMA receptacles includes congurations for virtually any packaging requirement, and we can supply any adapter or accessory you may need to complete your system design. Adapters between SMA and other series are shown starting on page 176. Many of our SMA connectors are available as MIL-PRF-39012 QPL versions. These types are listed starting on page 195. As with our other connector series, Deltas customer-driven design results in SMA series connectors with practical and unique features that make your design and assembly process easier. Some of these include: One-Step cable connectors for quick, accurate assembly to semi-rigid cable. PressMount receptacles (page 115) mount securely in a single round hole, saving space on your components and reducing your housing fabrication costs. Panel receptacles with ange sizes to match the same hole pattern as standard BNC, TNC or N connectors, letting you drill one hole pattern and mount BNC, N, SMA, TNC, or 7/16 series connectors as needed. Edge-mount P.C. board receptacles (page 114). Our new E-Line brass SMA connectors provide a lower-cost alternative for commercial applications (page 123). Our SMA series product line is still growing, so please call if you dont see what you need.
