The newly added multi-functional products of the Cardinal product family, which have been verified on-site, support the highest frequency band and offer unparalleled signal integrity and return loss performance. 

Through meticulous design, it can address the complexity of multi-channel signal routing in complex testing environments. 

Supports a data characterization transmission rate of up to 448 Gbps, which can be verified for next-generation AI clusters, 5G/6G, satellite communications, millimeter-wave radars and terahertz imaging. 

Lisle, Illinois - March 25, 2026 - Global leader in electronic equipment and innovator in connection technology, Molex (Cardinal) has launched high-frequency coaxial components with multiple ports, setting a new industry standard for testing and measurement (T&M). This product supports frequencies up to 145 GHz, marking a strategic expansion of the Cardinal family. Its mature and reliable mechanical integrity has further evolved and now meets the demands of high-bandwidth spectrum, and can be used to verify next-generation AI-driven architectures and 6G wireless infrastructure. 

Roman Buff, the general manager of Molex's RF division, said: "Expanding to 145 GHz is a natural evolution of the Cardinal product line, which is designed to meet the increasing demand for port density while ensuring that signal integrity is not compromised. This new high-speed solution integrates high-frequency contact technology into the Cardinal multi-port housing, helping engineers bridge the gap from AI to 6G and utilize existing infrastructure to test future-oriented chips." 

Take the lead in the test 

Although 110 GHz has always been the benchmark for high-performance testing, the surge in 6G research and the increasing demand for AI backhaul has raised even higher requirements. Molex's new 145 GHz Cardinal product is capable of analyzing the characteristics of signals that were beyond the reach of previous standard coaxial interfaces. The new component offers a phase-matching accuracy of up to 145 GHz connection, and after optimization, it can achieve extremely low insertion loss and excellent return loss performance at extreme frequencies. 

This brand-new Cardinal solution also supports a data characterization transmission rate of up to 448 Gbps, and can be used in conjunction with next-generation devices and systems. By breaking through measurement limits, this multi-functional product helps engineers verify the chips and network protocols that will define global connectivity in the next decade while meeting current standards. 

Configurable multi-port advantages 

The multi-port design of the Cardinal component is compact and sleek, supporting high-density testing simultaneously and shortening the development cycle. The new component can be seamlessly integrated into the Cardinal product ecosystem, providing high-performance connection solutions for a wide range of industry sectors, covering emerging demands such as next-generation AI clusters, 5G/6G infrastructure, satellite communication, millimeter-wave radar, and terahertz imaging. 

Molex integrates multiple RF connectors into a single multi-port housing, thereby shortening the testing cycle and reducing the total cost of ownership (TCO). High-performance RF connectors and compressed installation, as well as solderless printed circuit board (PCB) mounting methods, enhance testing flexibility and shorten installation and rework times. Integrating high-frequency contact technology into multi-port components enables engineers to exceed the 110 GHz testing limit, smoothly transition to the 145 GHz level, and achieve a smooth upgrade. 

Consistent and repeatable performance 

One of the key features of Molex's Cardinal components is the repeatability of connector alignment, which is crucial in environments where frequent connection and disconnection tests are conducted. The alignment quota of Cardinal multi-port high-frequency coaxial components exceeds 500 times, demonstrating reliable performance. What's more important is that Molex uses highly precise connectors to enhance repeatability, ensuring consistency and repeatability from the first measurement to the 500th measurement. 

This high-density PCB connector can minimize the space occupied by the circuit board, thereby enabling a smaller evaluation board and further reducing costs. 

Product supply 

The Molex Cardinal multi-port high-frequency coaxial module is now available on the market. The Cardinal 145 GHz module will be added to the existing product line, together with the 67 GHz precision coaxial module and the 110 GHz precision coaxial module, to form a complete solution. The Cardinal module also offers various connector options, including vertical, right-angle, and side-jointed PCB terminals, and provides scalable multi-port configurations, including 1x4, 1x8, and 2x8 configurations for high-density setups.
