3.5mm to 3.5mm Adapter, 33GHz Extended Frequency Stainless Steel | Precision Port Saver

Our 3.5mm to 3.5mm adapters are engineered for high-performance environments requiring frequencies up to 33GHz. While standard 3.5mm interfaces are limited to 26.5GHz, our precision extended frequency design allows for seamless operation across the Ka-Band and 5G FR1/FR2 bands. Manufactured from passivated stainless steel (SUS303), these adapters serve as essential Port Savers for expensive VNAs and signal generators, protecting your equipment ports from wear while maintaining metrology-grade signal integrity.

• Question: Why use a 33GHz 3.5mm adapter instead of a standard 26.5GHz one?
• Answer: "Many modern SATCOM and 5G applications operate in the 27GHz to 31GHz range. A standard 26.5GHz 3.5mm adapter may introduce unwanted reflections or moding in these bands. Our 33GHz 3.5mm adapter provides the necessary frequency headroom for these applications without the cost of moving to a 2.92mm (40GHz) system.
