● Precision Inter-Series Adaptation: Seamlessly bridges N-Type Female ports (test equipment, base stations, antenna systems) to SMA Male connections (WiFi modules, SDR devices, compact RF instruments) without additional adapters or signal degradation.
● Straight-Body Design: The straight (inline) configuration maintains axial alignment, minimizing signal reflection and providing the lowest possible VSWR compared to right-angle adapters — ideal for precision test setups and critical signal paths.
● Gold-Plated Beryllium Copper Center Contact: Beryllium copper provides superior spring contact force and fatigue resistance, while gold plating ensures minimal contact resistance and exceptional corrosion protection over thousands of mating cycles.
● PTFE Dielectric: Virgin PTFE (Teflon) insulator delivers outstanding electrical properties with a dielectric constant of 2.1 and loss tangent of 0.0002, maintaining stable impedance across the full 6 GHz frequency range.
● CNC Precision Machined: Every adapter body is CNC-machined from solid brass bar stock to tolerances of ±0.02mm, ensuring consistent impedance matching and reliable mechanical coupling.
● 100% VNA Lab Tested: Each production lot is validated using Rohde & Schwarz and Anritsu VNAs to verify VSWR, insertion loss, and impedance characteristics across the full frequency spectrum.
● In-Stock & Rapid Dispatch: Standard N Female to SMA Male adapters are maintained in high-volume inventory for same-day or next-day shipment worldwide.
The Essential Bridge Between Two RF Worlds
In the diverse landscape of RF connectivity, few challenges are more common than interfacing between N-Type and SMA connector systems. N-Type connectors dominate in infrastructure applications — base stations, test equipment, antenna systems, and broadcast installations — while SMA connectors are ubiquitous in compact devices, PCB-mounted modules, SDR transceivers, and precision instrumentation. Our N Female to SMA Male straight adapter eliminates the need for cumbersome multi-adapter chains, providing a single, precision-machined solution that preserves signal integrity.
Why Straight Adapters Outperform Right-Angle Versions
While right-angle adapters offer convenience in tight spaces, they inherently introduce additional signal reflection at the 90° bend — typically adding 0.05 to 0.1 dB of insertion loss and degrading VSWR by 10-20%. For applications where signal integrity is paramount — spectrum analysis, vector network analysis, precision antenna measurements, and high-speed data links — our straight adapter delivers measurably superior performance with VSWR as low as 1.15:1 up to 3 GHz.
Built for Demanding Environments
Manufactured by our senior RF engineering team with over 20 years of hands-on experience, these adapters are designed for professionals who demand reliability. The brass body provides excellent RF shielding and mechanical strength, while the choice of gold or nickel plating ensures long-term environmental protection. PTFE dielectric maintains stable electrical performance across extreme temperature ranges from -65°C to +165°C, making these adapters suitable for everything from Arctic field deployments to high-temperature industrial ovens.
Quality Assurance at Every Stage
Our manufacturing process follows strict ISO-aligned quality protocols:
1. Incoming Material Inspection — Every brass bar and PTFE rod is inspected for composition and purity.
2. In-Process CNC Monitoring — Dimensional checks at critical machining stages ensure ±0.02mm tolerance compliance.
3. Plating Quality Control — Gold plating thickness verified at 50μin (1.27μm) minimum for MIL-STD-202 corrosion resistance.
4. Final VNA Testing — 100% of production lots are tested on Rohde & Schwarz and Anritsu VNAs for VSWR and insertion loss verification.

Q1: What's the difference between "Jack" and "Female" / "Plug" and "Male"?
A: In RF terminology, "Jack" and "Female" are synonymous — both refer to the connector with the receptacle (inner socket) and internal threads. "Plug" and "Male" refer to the connector with the protruding center pin and external threads. In this adapter: N-Type Jack = N-Type Female, SMA Plug = SMA Male.
Q2: Can I use this adapter at 2.4 GHz for WiFi applications?
A: Absolutely. This adapter is rated DC – 6 GHz with VSWR ≤ 1.25, making it perfectly suited for 2.4 GHz and 5 GHz WiFi applications. For optimal performance at 5 GHz+, we recommend torquing both connections to specification.
Q3: Will this adapter work with RP-SMA connectors?
A: No. RP-SMA (Reverse Polarity SMA) has a reversed center pin configuration — the male plug has a receptacle instead of a pin. This adapter features standard SMA Male with a protruding center pin and will NOT mate with RP-SMA female connectors. We offer RP-SMA versions — please contact us for availability.
Q4: Is gold plating better than nickel plating for this adapter?
A: Gold plating offers superior corrosion resistance and lower contact resistance, making it ideal for precision test applications and harsh environments. Nickel plating is more cost-effective and provides good durability for general-purpose and indoor use. We offer both options — gold is standard, nickel available upon request.
Q5: Can I use this adapter outdoors?
A: The N-Type end provides excellent weather sealing when properly mated and torqued. The SMA end offers moderate weather resistance. For permanent outdoor installations, we recommend applying self-amalgamating weatherproofing tape over the SMA connection. For fully outdoor-rated solutions, consider our N-Type to N-Type adapters.
Q6: What is the power handling capability?
A: This adapter can handle approximately 500W CW at frequencies below 1 GHz and 100W at 6 GHz. Power handling is limited by the SMA connector's smaller contact geometry. For high-power applications above 500W, we recommend staying within the N-Type connector ecosystem.
Q7: Do you provide VNA test reports with orders?
A: Yes. We can provide VSWR and insertion loss test reports generated by our Rohde & Schwarz and Anritsu VNAs for bulk orders upon request. Sample orders include basic QC verification documentation.
