    SMA to AMC4

    Amphenol RF is excited to introduce the small form factor AMC4 connector as part of an SMA cable assembly line. This assembly features the popular SMA bulkhead jack connector and the newly minted AMC4 plug connector on 1.13mm cable. The SMA to AMC4 cable assembly is ideal for IoT applications which require space efficient, economical designs.

    These SMA to AMC4 cable assemblies offer excellent electrical performance from DC to 6 GHz and operate at 50 ohms. The new configuration is available in straight jack to right-angle plug and in standard metric lengths of 0.05, 0.10, 0.15, 0.20, 0.25, and 0.30. Custom lengths are available upon request.

    The AMC4 connector is currently the smallest connector in the Amphenol RF portfolio. It shares a similar footprint with the previously released AMMC connector and offers all the same benefits as the AMC interface, but in a more compact package size. This 50 ohm connector offers excellent electrical performance from DC to 6 GHz and is interchangeable with both the I-PEX MHF4 and Murata HSC connectors. The stand-alone version of the AMC4 connector will be available shortly.

    Amphenol RF’s HD-EFI product series is designed to maximize radial and axial float in board-to-board applications.

    Amphenol RF is proud to release its newly developed HD-EFI product line. This 50 ohm micro-miniature interface is ideal for blind-mate situations and mating multiple RF lines between printed circuit boards. These connectors are designed specifically to maximize radial and axial float in board to board applications.

    HD-EFI PCB jacks are available in through-hole, surface mount, and edge launch designs. The three-piece mating system uses a limited detent and a smooth bore PCB connector, joined by a floating bullet adapter in between. The generous gathering cone and unique bullet design allows for 1.4mm of axial float, and 1.4mm of radial float, with a maximum float angle of 5 degrees.

    These 50 ohm products have an operating frequency of DC to 6 GHz, making them ideal for high-performance applications with a small package size. The selection of PCB mounts and bullet lengths offer versatility for board launches and PCB stacking configurations.

    HD-EFI bullet adapters are uniquely designed to provide a crash-proof mating, facilitated by the extension of the insulator beyond the adapter body. Used in conjunction with the smooth bore connectors, the mating system allows for easy alignment and a secure connection.
