Richardson Electronics Expands Microwave Product Portfolio with Junkosha Cable Assemblies

0.8mm Connectors for Applications Up To 145 GHz

LaFox, IL, March 26, 2021– Richardson Electronics, Ltd. (NASDAQ: RELL) announced today the availability of Junkosha’s MWX004 interconnect cables.

Cables in the MWX004 series come with 1.0mm or 0.8mm connectors and include Junkosha’s patented “safety lock” feature, which prevents bending and breakage of the center pin. Since the maximum frequency for 5G is currently 71 GHz, this cable is ideal since it allows the evaluation of second harmonic spurs. Industry leading delivery of 2-3 weeks for custom cable lengths.

With over 60 years of industry-leading experience in the RF market, Junkosha’s next generation of cables and interconnects for the 5G industry stand up to the rigors of higher frequencies while operating efficiently in environments with high flexure and temperature change.

“Junkosha’s new products fit perfectly into our Microwave portfolio and our growth strategy. We are well-positioned for continued growth, and will continue to provide our customers with cutting-edge technology and products,” said Greg Peloquin, Executive Vice President of Richardson Electronics’ Power & Microwave Technologies group.
