Pre-configured SMPM Cable Assemblies Offer Flexibility In Compact, High Frequency Applications

March 13, 2025

Amphenol RF announced the expansion of their cable assembly portfolio with new cable assemblies engineered with straight SMPM plug connectors on compact 0.047-in. cable. SMPM connectors offer reliable, high frequency performance in a compact package and are designed to accommodate both radial and axial misalignment. Coupled with the flexible capabilities of the cable, this assembly is ideal for board-to-board, quantum computing and medical applications which require high reliability.

These SMPM cable assemblies operate up to 18 GHz with a generous minimum bend radius of 0.05 in. The cable is engineered to be a versatile micro-coaxial cable for designs that require a high-density solution. The flexibility of the cable allows for easy routing, aided by the push-on coupling mechanism of the SMPM plug connectors for easy mating and unmating, making these assemblies extremely versatile. They are available in standard lengths starting at 3 in. and compliment any RF design. Custom lengths are available upon request.

These cable assemblies join a robust portfolio of pre-configured SMPM options designed to accommodate a variety of cable types. SMPM cable assemblies are a good fit for applications exposed to shock and vibration such as instrumentation equipment, aerospace and military/defense applications where commercial off-the-shelf products are suitable.
