New Samtec SMA Interconnects Capable of 26.5 GHz

Why It Matters

The connector enables higher‑frequency signal integrity for emerging 5G/6G infrastructure, reducing system‑level loss and simplifying board layouts. Its immediate availability and design support give OEMs faster time‑to‑market in competitive RF sectors.

Key Takeaways

• Samtec’s new SMA edge‑mount connector supports up to 26.5 GHz.
• 50 Ω impedance design reduces return loss versus vertical connectors.
• Gold‑plated contacts enable 500 mating cycles and corrosion resistance.
• Compatible with low‑loss coax cables ranging .047‑.277 in diameter.
• Available now; Samtec offers RF launch optimization and design support.

Pulse Analysis

The race to higher‑frequency wireless standards such as 5G and the nascent 6G ecosystem is driving a surge in demand for interconnects that can preserve signal integrity at gigahertz speeds. Traditional right‑angle SMA connectors introduce parasitic inductance and impedance mismatches that degrade performance, especially above 20 GHz. By mounting directly on the PCB edge, Samtec’s SMA solution shortens the signal path, curtails discontinuities, and delivers a consistent 50 Ω environment, which is critical for maintaining low return loss in high‑speed RF chains.

Beyond the electrical advantages, the connector’s mechanical design addresses durability concerns common in aerospace and military applications. A four‑post through‑hole mount reinforces the solder joint, while gold‑plated contacts and a corrosion‑resistant body support up to 500 mating cycles without performance drift. The product line also offers flexibility through compatible low‑loss coaxial cables ranging from .047 to .277 inches in diameter, allowing engineers to tailor loss and bend‑radius characteristics to specific system constraints. This modularity accelerates prototype iteration and reduces inventory complexity for OEMs.

Samtec’s $1 billion global footprint and extensive RF design services further amplify the connector’s market impact. With in‑stock availability and on‑demand launch optimization—including e‑field simulation and 3D modeling—customers can shorten development cycles and mitigate costly redesigns. The announcement positions Samtec as a go‑to supplier for high‑frequency interconnects, reinforcing its role in the supply chain that underpins next‑generation telecom, defense, and test‑and‑measurement sectors. As the industry pushes toward ever‑higher frequencies, solutions that combine performance, reliability, and rapid support will be decisive differentiators.
