Samtec has introduced the 185-AL Series, a 1.85 mm board launch connector that exits the PCB at a 30-degree angle instead of vertically. Designed for millimeter-wave test and evaluation boards, the connector is specified to 67 GHz and addresses cable routing and connector replacement challenges common in high-frequency development.
The angled launch changes the direction in which the coaxial cable leaves the board, reducing the tight bends that often occur immediately after a conventional vertical launch. According to Samtec, this helps maintain more consistent electrical performance while simplifying cable management on densely populated test fixtures.
30° Launch Geometry
As operating frequencies increase, the physical routing of RF cables becomes a more significant consideration during board design and testing. Sharp bends close to the connector can affect measurement repeatability and make densely packed evaluation boards more difficult to work with.
The 185-AL Series redirects the cable away from the PCB at a 30-degree angle, allowing a more gradual cable path while retaining compatibility with 1.85 mm interconnects specified through 67 GHz.
Solderless Compression Mount
Rather than using a soldered board launch, the connector is secured using a compression-mount design. According to Samtec, this allows connectors to be installed, removed, and reused without solder reflow, making them field replaceable during development and evaluation. Removing the solder process also eliminates variations associated with soldered launches, supporting more repeatable RF measurements.
The connector uses a threaded coupling for mechanical retention and is compatible with several of Samtec's microwave cable assemblies, including the RF047-A, RF086, and Nitrowave LL071 Series.
The 185-AL Series is available in production quantities directly from Samtec.

Technology Overview
Samtec's 185-AL Series is a 1.85 mm RF board launch connector for applications through 67 GHz. The connector combines a 30-degree angled launch with a solderless compression-mount design, allowing field replacement while reducing cable bend immediately above the PCB in millimeter-wave test and evaluation systems.
Frequently Asked Questions
What frequency does the Samtec 185-AL Series support?
The connector is specified for operation through 67 GHz.
Why does the connector use a 30-degree launch?
The angled geometry allows coaxial cables to leave the PCB with a gentler bend than a conventional vertical launch, reducing routing constraints on dense RF test boards.
Is the 185-AL Series soldered to the PCB?
No. The connector uses a compression-mount design that allows installation and removal without solder reflow.
