Molex's Breakthrough in High-Frequency Testing

Molex, a prominent figure in the electronics industry, has recently introduced an innovative product designed to redefine standards in Test and Measurement (T&M). The company's new Cardinal Multi-Port High-Frequency Coaxial Assemblies, capable of supporting frequencies up to 145 GHz, marks a significant advancement in the testing infrastructure required for the next generation of AI-driven technologies and 6G wireless communication.

Evolution of the Cardinal Product Line

The introduction of the Cardinal assemblies represents a natural progression in the product line, responding to the increasing demands for higher frequencies and better signal integrity in testing environments. Roman Buff, the general manager for RF at Molex, emphasizes that this latest offering builds on the established mechanical integrity of the Cardinal series, pushing boundaries to accommodate the demanding requirements of multi-channel signal routing in complex test setups.

As industries embrace advancements in AI and 6G technologies, the need for efficient data characterization mechanisms becomes critical. The 145 GHz Cardinal assembly is designed to operate at exceptional data rates of up to 448 Gbps, making it suitable not only for AI clusters but also for other advanced implementations like 5G/6G infrastructures and mmWave radar systems.

Addressing Industry Challenges

Historically, 110 GHz has been the upper limit for high-performance testing tools. However, as the race for 6G technology gains momentum, researchers and engineers have begun searching for better solutions to address new challenges that standard coaxial interfaces could not meet. Molex’s 145 GHz assembly promises to fill that gap, allowing users to characterize signals that were previously difficult to test.

When it comes to reducing insertion loss and improving return loss performance, this new product excels. The result is a versatile solution that not only meets current industry standards but also prepares engineers for the rapid advancements expected in the next decade of global connectivity.

The Multi-Port Advantage

One of the distinguishing features of the new Cardinal assemblies is their multi-port design. This functionality enables simultaneous, high-density testing within a compact footprint, which dramatically accelerates the research and development processes for industry professionals. Molex's innovative approach allows the consolidation of multiple RF connectors into a single housing unit, which translates to reduced testing cycles and overall costs.

Moreover, the high-performance RF connectors, combined with a compression-mounted, solderless PCB attachment, contribute to enhanced testing flexibility while minimizing the time needed for installation and any potential rework.

The adaptability of the high-frequency contact technology within the Cardinal assemblies provides engineers with a seamless transition from existing 110 GHz capabilities to the new 145 GHz standards. This transition not only preserves connective security but also standardizes testing processes across various applications.

Reliable, Consistent Performance

Commitment to quality is a hallmark of Molex's offerings. The Cardinal Multi-Port Coaxial Assemblies are engineered to provide consistent performance over 500 connection cycles, ensuring that reliability doesn't wane with frequent use in dynamic testing environments. The precision in connector design guarantees that engineers experience repeatable performance from their very first to their most recent measurements, which is critical in high-stakes testing scenarios.

Additionally, the streamlined PCB connector dimensions contribute to a reduction in board real estate, leading to smaller evaluation boards and further cost savings for customers.

Availability and Future Prospects

The Cardinal Multi-Port High-Frequency Coaxial Assemblies are available for purchase now, complementing the existing line of 67 GHz and 110 GHz Precision Coaxial Assemblies. With various connector configurations such as vertical, right-angle, and edge-mount PCB terminations, the Cardinal assemblies allow for high-density setups across different applications of RF and microwave testing.

Molex will showcase its new high-speed technologies at DesignCon 2026, where professionals can see firsthand the advancements in the Cardinal assembly's capabilities alongside their other innovative solutions designed for next-generation connectivity.

In closing, Molex not only continues its legacy of excellence in electronics but also pioneers pathways into future technologies, affirming its role in shaping the very fabric of global communication.
