Samtec Glass Core Technology was Popular at IMS 2025
Samtec glass core technology, or GCT, offers many benefits when compared to silicon or organic substrates, particularly at mm-wave frequencies and beyond. This includes an exceptional loss tangent, embedded passive components, less variation between components, and other advanced packaging capabilities.
Instead of me telling you the benefits of glass, please check out this video from Nokia Bell Labs’ Shahriar Shahramian. Shahriar says that GCT is “a new paradigm in packaging. It’s really the next step to bring … really complex mixed-signal devices together.”
Several companies at IMS displayed products powered by Samtec glass core technology. This video provides a brief overview of six of those applications.
NORTHROP GRUMMAN displayed a far-reach E Band backhaul on glass. It utilizes silicon germanium and gallium nitride on glass.
MILLIBOX uses Samtec glass core technology in a J Band 300 GHz antenna on glass.
KEYSIGHT One of the demos at the Keysight booth featured a D Band radio on glass module, for multi-kilometer wireless backhaul links. It contains four separate radios on glass. It won one of the Best Paper Awards at IMS 2025.
MENLO MICRO showcased a high-speed digital switch for IC testing, including AI GPUs. These switches utilize Samtec glass core technology.
NOKIA BELL LABS had two demos at the Samtec booth. One showed how they utilized Samtec glass core technology (GCT) to develop an E band radio on glass. The other showed the superior performance of glass substrate over organic substrates, as demonstrated in a 7-pole bandpass filter.
