Description
SMB to N L-Adaptor | Snap-lock & Screw-lock | Brass & Beryllium Copper Body
The ROSNOL ADL-S1N25A/H91-H4 is a precision-engineered L-adaptor featuring an SMB plug (male) to N jack (female) configuration, supporting frequencies from DC to 4 GHz with a maximum VSWR of 1.17. It offers low insertion loss (≤ 0.05 × √F GHz dB), high insulation resistance (≥ 1 GΩ), and excellent RF leakage performance (≥ 55 dB up to 1 GHz). The adaptor ensures robust mechanical reliability with a minimum of 500 mating cycles on both ends, and coupling mechanisms include snap-lock for the SMB side and screw-lock for the N side.Constructed with high-grade materials, the SMB side features a beryllium copper body and phosphor bronze center contact, both gold-plated with non-magnetic nickel-phosphorus underplating. The N side utilizes a brass body with copper-tin-zinc alloy plating and a phosphor bronze center contact with gold plating. All insulators are made of PTFE. This adaptor is compliant with RoHS standards and designed to operate within a temperature range of -55°C to +155°C.
ROSNOL’s precision-engineered RF adapters deliver reliable performance across a wide range of RF and microwave systems. Designed to meet the stringent demands of high-frequency signal transmission, ROSNOL adapters offer a cost-effective alternative to products from leading European and American brands. All ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring global environmental and safety standards. Customization services for materials, plating, and mechanical design are available to support specialized interconnect requirements.
