Description
SMA Jack (Female) to MHFIV Jack (Female) Straight RF Adapter | Screw-Lock & Snap-Lock | Brass Body
The ROSNOL AD-A2MHFIV25A/91-91 straight RF adapter offers secure connectivity between SMA jack (female) and MHFIV jack (female), operating from DC to 6 GHz with 50-ohm impedance. It achieves VSWR ≤ 1.40 (≥ 15.6 dB return loss), insertion loss ≤ 0.05 × √F (GHz) dB, and insulation resistance ≥ 1 GΩ. Test voltage is rated at 750 V rms, with working voltage of 335 V rms and maximum contact current of 1.5 A DC. Mechanical integrity includes screw-lock coupling for SMA and snap-lock for MHFIV, axial captivation ≥ 27 N, and recommended torque of 0.8–1.1 Nm for SMA.Constructed for reliability, the adapter uses beryllium copper center contacts with gold plating over nickel-phosphorus underlayer, brass bodies with gold finish, and PTFE insulators for superior dielectric properties. This design ensures robust performance for compact RF systems.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across RF and microwave systems. Designed to meet stringent high-frequency requirements, ROSNOL adapters provide a cost-effective alternative to leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Customization for materials, plating, and mechanical design is available to meet specialized interconnect needs.
