How MACOM Technology Solutions (MTSI) Is Using Hot Via Packaging to Support Faster AI Networking Components

MACOM Technology Solutions Holdings, Inc. (NASDAQ:MTSI) is one of the Best Fiber Optics Stocks to Buy for the AI Data Center Boom. On June 8, 2026, MACOM introduced its hot via chip scale technology, a packaging process built on AlGaAs diode technology that eliminates traditional wire bonds. The product detail is technical, but the investor angle is straightforward: as AI networks move toward faster optical and high-frequency links, component makers need packaging that can preserve signal quality while reducing assembly complexity.

MACOM said the process routes RF signal and ground paths vertically through the die, simplifying surface-mount assembly, reducing parasitics, improving manufacturing consistency, and supporting reliable performance into millimeter-wave frequencies. Its first product using the process is the MASW-011261, a broadband SP2T switch operating from 60 to 110 GHz, with 0.9 dB typical insertion loss, 30 dB isolation, and sub-20 ns switching. The release reinforces MACOM’s position in high-speed semiconductor components used across optical networking and data-center infrastructure.
