1.85mm Plug (Male) to Precision SMA Plug (Male) Adapter, DC-27 GHz VSWR 1.15

1.85mm Plug (Male) to Precision SMA Plug (Male) Adapter | Straight Design | Screw-Lock | Stainless Steel Body

The ROSNOL AD-V1PCA15A/9XX-9XX is a precision 50-ohm straight adapter designed for DC to 27 GHz operation, delivering VSWR ≤ 1.15 (≥ 23.13 dB return loss) and insertion loss ≤ 0.05 × √F (GHz) dB. It ensures robust electrical performance with center-contact captivation ≥ 20 N and ≥ 27 N on respective sides, and mechanical durability rated at ≥ 500 mating cycles. Both ends feature screw-lock coupling for secure engagement, with recommended torque of 0.80–1.10 Nm and test torque up to 1.65 Nm and 1.70 Nm.

Constructed with beryllium copper center contacts plated with 3 microinch gold over an 80 microinch non-magnetic nickel-phosphorus underplating, this adapter guarantees excellent conductivity and corrosion resistance. Stainless steel bodies and coupling nuts are passivated for durability, while PS insulators provide stable dielectric properties. The design supports reliable operation across a temperature range of −60°C to +100°C.

ROSNOL’s precision-engineered RF adapters deliver consistent performance for RF and microwave systems at competitive pricing, making them an ideal alternative to leading European and American brands. All ROSNOL components are manufactured in ISO 9001-certified facilities and comply fully with RoHS and REACH standards. Customization services for materials, plating, and mechanical design are available to meet specialized interconnect requirements.
