Molex Cardinal coaxial assemblies reach 145 GHz frequency

Molex has introduced Cardinal Multi-Port High-Frequency Coaxial Assemblies supporting frequencies up to 145 GHz, extending a product family previously capped at 110 GHz. The new assemblies support data characterisation up to 448 Gbps and are targeted at testing environments for AI clusters, 5G/6G infrastructure, satellite communications, and mmWave radar.

The multi-port design consolidates multiple RF connectors into a single housing, enabling simultaneous high-density testing in a compact footprint. Connectors use solderless, compression-mounted PCB attachment and are rated for 500 mating cycles. Phase-matched connections are optimised for minimal insertion loss at extreme frequencies.

Available configurations include 1×4, 1×8, and 2×8 multi-port layouts, with vertical, right-angle, and edge-mount PCB termination options. The 145 GHz assemblies join existing Cardinal lines at 67 GHz and 110 GHz. Molex is showcasing the product at DesignCon 2026 in Santa Clara, running 24 to 26 February.
