High Frequency N Male to SMA Female Adapter

Description

The High Frequency N Male to SMA Female Adapter is a high-performance “between-series” microwave component designed for applications where standard RF adapters fail to meet strict spectral requirements. It features an N-Type Plug (Male) on one side and an SMA Jack (Female) on the other. Unlike standard versions limited to 3 or 6 GHz, this high-frequency variant is precision-machined with tighter tolerances and enhanced internal geometries to support frequencies up to 18 GHz.

This adapter is essential for microwave engineers and technicians who need to interface SMA-terminated cables or components with N-Type female test ports on Vector Network Analyzers (VNA), signal generators, and spectrum analyzers. Its design focuses on minimizing signal reflections and phase distortion, making it ideal for high-speed data transmission, aerospace, and defense applications. Constructed with a passivated stainless steel or high-grade tri-metal plated brass body and PTFE (Teflon) insulation, it ensures long-term electrical stability and mechanical reliability under repeated use.

Key Technical Advantages

• Extended Frequency Range: Optimized to provide consistent performance up to 18 GHz, far exceeding the limits of standard general-purpose adapters.

• Low VSWR & Insertion Loss: Engineered with precision internal transitions to ensure minimal signal reflection and power attenuation across the entire frequency spectrum.

• Precision RF Shielding: The robust metal housing provides a continuous ground path, ensuring maximum EMI/RFI protection in sensitive high-frequency environments.

• Superior Mechanical Durability: Built to withstand frequent mating cycles in laboratory settings without degrading electrical performance or physical tolerances.

• Enhanced Signal Integrity: High-purity gold-plated center contacts ensure ultra-low contact resistance and superior signal conductivity for critical microwave measurements.

Key Features

• N Male to SMA Female Interface: Consists of an N-Type Plug (with center pin and hex coupling nut) and an SMA Jack (with socket and external threads).

• Passivated Stainless Steel or Tri-Metal Construction: Offers exceptional corrosion resistance and mechanical hardness for professional-grade durability.

• High-Performance PTFE Dielectric: Provides superior thermal stability and maintains a constant dielectric constant across high frequencies.

• Standard 50 Ohm Impedance: Specifically engineered to match standard high-performance microwave test instrumentation and communication systems.

• Precision-Threaded Interface: Complies with international standards (MIL-STD-348B) to ensure perfect alignment and contact during mating.
