Description

This SMA female to stripping head cable is a semi-rigid coaxial assembly designed for prototyping and integrating RF subsystems. The SMA female connector features a central receptacle and a threaded outer barrel, engineered for reliable mating with standard SMA male interfaces commonly found on Wi-Fi, cellular, and LoRa modules. The opposite end is stripped, with the center conductor and shield separated and pre-tinned, ready for direct soldering to custom antenna traces, test points, or development board headers.

The RG1.13 cable construction maintains a consistent 50-ohm characteristic impedance, critical for minimizing signal reflection and loss in high-frequency wireless links from DC to 18GHz. The use of polytetrafluoroethylene (PTFE) dielectric and metal-shell connectors ensures mechanical durability and stable electrical parameters across temperature variations, making it suitable for both lab bench testing and field-deployed IoT hardware.

Key Features

  • SMA female connector with 36 threads-per-inch coupling for secure, vibration-resistant antenna attachment.
  • Stripped and tinned cable end facilitates custom wiring, soldering to PCB antennas, or connection to screw terminals.
  • 50-ohm RG1.13 coaxial cable optimized for minimal VSWR in Wi-Fi (2.4/5GHz), cellular (4G/LTE), and ISM band (433MHz, 868MHz, 915MHz) applications.
  • PTFE dielectric and nickel/gold-plated contacts ensure low insertion loss and corrosion resistance for long-term reliability.
  • 15cm length provides sufficient reach for internal antenna routing within embedded enclosures or test setups.
  • Note: Compatible with standard SMA (not RP-SMA) interfaces; verify connector polarity before installation.

Applications

  • Prototyping custom PCB antennas for ESP32, Raspberry Pi, or LoRaWAN modules.
  • Extending internal antenna connections to external SMA mounts on IoT gateways or routers.
  • Creating test leads for RF signal analysis with VNAs or spectrum analyzers.
  • Wiring RF front-end components in amateur radio, drone FPV, or telemetry systems.
  • Connecting cellular (4G/LTE) or GPS/GNSS modules to external high-gain antennas.

Frequently Asked Questions

What is the impedance of this SMA cable, and why is it important?

The cable has a 50-ohm characteristic impedance, which is the standard for most RF and wireless communication systems like Wi-Fi, cellular, and LoRa. Matching impedance between the cable, connector, and antenna minimizes signal reflections (high VSWR), ensuring maximum power transfer and reducing loss, which is critical for maintaining link range and data integrity in IoT applications.

Can I solder the stripped end directly to my ESP32's antenna pin?

Yes, the stripped and tinned end is designed for direct soldering. The center conductor should be soldered to the RF output pin or antenna trace on your ESP32 or other wireless module, while the braided shield should be connected to the board's ground plane. Use minimal solder and keep the connection short to avoid introducing impedance mismatches or parasitic capacitance that could degrade high-frequency performance.

Is this cable compatible with RP-SMA connectors commonly found on consumer routers?

No, this cable uses a standard SMA female connector, which is not mechanically compatible with Reverse Polarity SMA (RP-SMA). The RP-SMA connector has a reversed gender configuration (female center pin, male outer thread). Attempting to mate them can cause damage. Always verify your device's connector type—standard SMA is typical for professional RF modules, while RP-SMA is often used on consumer Wi-Fi equipment.
