This 5cm RG1.13 coaxial cable features an SMA female connector on one end and a stripped, tinned termination on the other, designed for custom antenna builds and direct PCB soldering in RF projects.

Features

  • Custom Termination: SMA female to stripped, tinned leads allows direct connection to PCBs, antenna elements, or custom RF circuits.
  • Precision RF Cable: Utilizes RG1.13 coaxial cable (approx. 1.13mm diameter) for controlled impedance and minimal signal loss over short runs.
  • Secure SMA Coupling: Female connector features a threaded barrel (36 TPI) for a secure, durable mechanical connection to SMA male jacks.
  • Compact Form Factor: Short 5cm length and 11mm connector are ideal for tight-space deployments inside enclosures or on development boards.

Description

This SMA female to stripping head cable is a fundamental RF interconnect for engineers and makers building custom wireless systems. The SMA female connector provides a standard, threaded interface for connecting to external antennas or test equipment, while the stripped and tinned opposite end offers flexibility for direct soldering onto PCB pads, antenna radiating elements, or terminal blocks. The use of RG1.13 coaxial cable ensures a consistent 50-ohm characteristic impedance, critical for maintaining signal integrity in Wi-Fi, cellular, GPS, and other RF applications up to several GHz.

Constructed with a brass or stainless-steel connector body and nickel or gold-plated contacts, the assembly offers good mechanical durability and reliable electrical conductivity. The 5cm length makes it particularly suitable for internal routing within compact IoT devices, drones, or sensor nodes, minimizing cable clutter and potential impedance mismatches. This cable is a practical solution for prototyping, repairing antenna links, or creating permanent installations where a pre-made pigtail is not suitable.

Key Features

  • Direct PCB Integration: Stripped and tinned end facilitates clean soldering to circuit board traces or through-hole pads, eliminating the need for an additional connector.
  • Controlled Impedance Path: RG1.13 coaxial cable maintains a stable 50-ohm impedance, reducing VSWR and signal reflections for improved RF performance.
  • Standard SMA Interface: Female SMA connector with external threads ensures a secure, screw-on connection compatible with a vast array of SMA male antennas and devices.
  • Durable Construction: Connector features a threaded coupling mechanism for excellent strain relief and mechanical stability in mobile or vibration-prone environments.
  • Flexible Deployment: Short length and small cable diameter allow for easy routing inside tight enclosures for embedded systems and compact IoT hardware.

Applications

  • Custom Antenna Fabrication: Solder stripped end directly to dipole elements, helical coils, or PCB trace antennas for Wi-Fi, Bluetooth, or LoRa devices.
  • PCB-to-Antenna Link: Connect an onboard RF module's SMA male port to an external antenna mounted elsewhere in an enclosure.
  • Test & Measurement Jigs: Create temporary connections for RF testing, spectrum analysis, or signal injection during development and debugging.
  • IoT Device Internal Wiring: Provide a reliable RF feedline between a module and an internal antenna in compact sensor nodes or trackers.

Frequently Asked Questions

What is the impedance of this RG1.13 cable, and why is it important?

The RG1.13 coaxial cable is designed for a nominal 50-ohm characteristic impedance. Matching impedance is critical in RF systems to prevent signal reflections, which cause high Voltage Standing Wave Ratio (VSWR), reduced power transfer, and potential damage to transmitter stages. Using this 50-ohm cable ensures maximum power delivery between your RF module's SMA port and the connected antenna or load, maintaining signal integrity for frequencies used in Wi-Fi, cellular, and GPS applications.

How do I solder the stripped end of this cable to my PCB?

First, separate the central conductor from the surrounding braided shield. Tin the exposed center conductor with a small amount of solder. Solder this conductor to your PCB's RF signal pad or antenna trace. Next, twist the braided shield together and tin it, then solder it to the designated ground plane or ground pad on your board. Keep the solder joint clean and minimal to avoid capacitive loading. Ensure the shield does not short to the signal line. A hot iron with a fine tip is recommended for precise work.

Can I use this cable to connect an SMA male antenna to a device without an SMA port?

Yes, this cable is ideal for that purpose. The SMA female end connects directly to your standard SMA male antenna. The stripped, tinned end can then be soldered directly to the appropriate points on your device's PCB. For example, you can solder the center conductor to the antenna output pin of a Wi-Fi module (like an ESP32) and the shield to the module's ground, effectively extending the antenna port. This method is common for embedding external antennas in custom enclosures or when the original device lacks a connector.

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

No, this cable uses a standard SMA female connector. Standard SMA and Reverse Polarity SMA (RP-SMA) are mechanically compatible but electrically reversed; the gender of the center pin/receptacle is swapped. Mating a standard SMA female (as on this cable) with an RP-SMA male may cause a short circuit. Always verify your equipment uses standard SMA interfaces. This cable is intended for standard SMA male ports found on many industrial RF modules, development boards, and test equipment.
