Description
IPEX I Plug (Male) to SMA Jack (Female) | Straight Design | Screw-Lock | Brass Body
The ROSNOL AD-MHFI1A25A/99-91 is a precision RF adapter operating from DC to 6 GHz with 50 ohm impedance. It achieves a VSWR of ≤1.3 and insertion loss below 0.25 dB, ensuring excellent return loss performance. Electrical specifications include dielectric withstanding voltage up to 500 Vrms, working voltage of 170 Vrms, and durability rated at 500 mating cycles.Engineered with premium materials, both sides use beryllium copper center contacts with gold plating over nickel underplating, brass bodies gold plated, and PTFE insulators for dielectric stability. A silicone rubber gasket enhances environmental sealing. The adapter operates reliably from −65°C to +155°C.
ROSNOL’s RF adapters deliver precision, consistency, and value, making them a competitive alternative to major European and American brands. All products are manufactured under ISO 9001 certified processes and comply fully with RoHS and REACH. Customization for materials, plating, and mechanical design is available to support specialized interconnect needs.
