MCX Female to SMA Female Adapter

MCX Female to SMA Female Adapter

High quality MCX Female to SMA Female Adapter products for precise RF connections are provided by SIPU RF Technology. Our model SIPU-MCX/SMA-KK has the characteristic impedance of 50Ω in the frequency range of DC-6GHz, and the insertion loss is ≤0.06√F(GHz)dB. The adapter has gold-plated beryllium bronze center contacts and brass outside conductors with contact resistance as low as <= 5.0mΩ (central) and <= 2.5mΩ (outer). With VSWR < 1.3, 500 mating cycle durability and operating stability from -65℃ to +125℃, this adapter enables stable interface transitions for telecommunications, test equipment and high frequency applications. The PTFE dielectric and 750V dielectric withstanding voltage provide stable functioning in harsh settings.

Product Overview

This is an interseries adapter from Micro coaxial (MCX) to Sub-miniature version A (SMA) with female jacks on both ends. The straight orientation design means that the connections may be made directly without the difficulty of further rotation or alignment.

Its compact design makes it ideal for space-constrained installations while maintaining signal integrity. Contact surfaces are gold-plated for improved conductivity and corrosion resistance in long-term deployment situations.

The snap-on MCX side mates to the threaded SMA side, providing a good compromise of quick-connect ease and secure mechanical connection. This hybrid approach provides flexibility in installation and ensures stable connections under operational stresses.

Key Advantages

The gold-plated contact surfaces deliver superior electrical performance and environmental protection. This plating choice reduces oxidation effects that commonly degrade signal quality in field deployments.

Low insertion loss characteristics preserve signal strength across the frequency spectrum. Your system maintains power efficiency without compensation for adapter-induced attenuation.

The beryllium bronze center contact provides consistent spring force throughout the 500-cycle lifespan. This material selection prevents contact degradation that affects measurement accuracy in test applications.

PTFE dielectric material ensures stable electrical properties across temperature extremes. Your installations benefit from predictable performance whether deployed in climate-controlled labs or outdoor enclosures.

The compact form factor enables integration into high-density RF assemblies. You gain interface flexibility without sacrificing board space or complicating mechanical layouts.

Application Scenarios

Telecommunications Infrastructure: Connect mini-PCIe or M.2 wireless cards with MCX ports to external SMA antenna systems in 5G base stations and industrial IoT networks.

RF Testing Environments: Interface miniaturized board-level components to standard SMA-terminated test equipment including vector network analyzers and signal generators.

GPS/GNSS Integration: Bridge compact GNSS modules to standard SMA antenna connections in automotive testing and aerospace development laboratories.

Prototyping Workflows: Enable rapid configuration changes when evaluating different antenna options or signal routing architectures during product development cycles.

The MCX Female to SMA Female Adapter serves critical roles where miniaturized MCX interfaces must connect to standardized SMA equipment without custom cable assemblies.

Quality Control Procedures

Each production batch undergoes dielectric withstanding voltage testing at 750V using insulation testers to verify electrical isolation integrity. Insulation resistance measurements confirm values exceed 5,000MΩ threshold requirements.

Plating quality verification includes thickness measurement and adhesion testing for both gold-plated layers. RoHS environmental compliance testing occurs for every manufacturing batch to ensure regulatory conformance.

The design structure inherently guarantees VSWR and insertion loss performance through precision machining and material selection. These parameters derive from geometric accuracy rather than individual unit testing.

Production processes maintain strict dimensional tolerances to ensure reliable mating with connectors meeting MIL-STD-348 specifications. Quality verification confirms mechanical compatibility across the rated 500 mating cycles.

Frequently Asked Questions

Q:What impedance system does this adapter support?

A:The adapter maintains 50Ω impedance throughout the signal path, making it suitable exclusively for 50-ohm RF systems common in telecommunications and instrumentation applications.

Q:Can this adapter handle outdoor installations?

A:The -65℃ to +125℃ operating range and gold-plated contacts provide environmental protection, though additional weatherproofing enclosures may benefit long-term outdoor deployments.

Q:How does insertion loss vary across the frequency range?

A:Insertion loss follows the formula ≤0.06√F(GHz)dB, meaning at 6GHz maximum frequency, insertion loss remains below approximately 0.15dB.

Q:What causes the 500-cycle mating limit?

A:The beryllium bronze center contact gradually loses spring tension through repeated insertions. The MCX snap-on mechanism also experiences wear on the detent features over cycling.

Q:Does contact resistance affect measurement accuracy?

A:The ≤5.0mΩ center contact resistance introduces negligible voltage drop in typical 50Ω systems, maintaining measurement integrity for precision test applications.
