Press Release

Leading international manufacturer of components and systems for optical and electrical connectivity, HUBER+SUHNER, is showcasing its smart concept solutions which offer increased power and lower running costs to RF-energy applications at the third Electronic Design Innovation Conference (EDI CON), in China, March 20-22.

Speaking today, Hannes Grubinger, Market Manager at HUBER+SUHNER, addressed the current challenges within the RF Energy market and highlighted the solutions which the company can offer to tackle these problems.

“Connectors and cables used in the communication industry today are often not the best-placed solution for RF-energy appliances. The losses and cost of coaxial assemblies are not appropriate for the applications in the respective markets, including cooking and warming, industrial, medical and automotive applications,” said Grubinger. “Using solid-state generated and amplified RF-power brings a completely new user experience due to the improved controllability of amplifiers compared to magnetrons.”

Grubinger emphasised having the right RF-connectivity is key to the future success of solid-state RF-based systems and stressed the need to provide a solution that overcomes mechanical stress between building blocks. According to Grubinger, a good RF-Energy connector solution needs to allow mounting with relative relaxed mechanical tolerances but must also provide an excellent electrical performance. Reaching the industries’ cost targets are another important detail.

He said: “The new HUBER+SUHNER RFEX connector has been developed to further integrate the RF-output connector into the housing of amplifiers used in RF-Energy. This reduces costs and maximises RF-performance. Features such as blind mateability and reduced mechanical stress, as known in HUBER+SUHNER MMBX, MFBX and MBX connectors, have also been implemented into the HUBER+SUHNER RFEX.”

The HUBER+SUHNER RFEX technology is designed for direct connection with dielectric-filled waveguides, rectangular waveguides or the appliance. This means that the antenna structure is part of the connector and can be implemented according to the customer’s needs. RFEX is designed for production of very high volumes, not only supporting the need of low component cost, but also supporting simplification of amplifier and appliance assembly processes.

Grubinger also drew attention to the idea that while distributing the RF-Energy by waveguides is common practice and a cost-effective method, dielectric-filled waveguides in complex applications may further reduce size and cost, allowing for higher installation flexibility. Since dielectric-filled waveguides are extruded, they can be manufactured in any length and format needed, providing significantly higher flexibility for application designers.

“Our breakthrough in alternative connectivity shows that many unsolved issues can now be solved by connecting solid-state RF-amplifiers with the new HUBER+SUHNER RF-connector solutions. The solutions contribute to higher achieving and performing appliances, cost benefits, and can be utilised for commercial solid-state energy use in the future,” concluded Grubinger.

Hannes Grubinger’s presentation is titled “RF-Energy-Connectivity, addressing the requirements of the future applications” and will take place at 12:05pm on March 20th. In addition to this, he will contribute to an RF-Energy panel session on March 22nd, “Solid State RF-Energy – Inroads to the Industrial Market, Panel Discussion” at 09:05am.
