Description

This 30cm RP-SMA Female to IPEX1 connector cable is a critical RF interconnect for wireless system integration. The RP-SMA (Reverse Polarity SMA) female connector is commonly found on wireless routers, access points, and external antenna ports, while the IPEX1 (or MHF1) micro-coaxial connector is the standard interface on most compact Wi-Fi, Bluetooth, LoRa, and cellular modules. The RG1.13 cable provides a balanced combination of flexibility and low signal attenuation, making it ideal for prototyping and final installations where space is constrained.

Proper impedance matching (typically 50 ohms) is maintained across the cable assembly to ensure minimal VSWR and maximum power transfer between your RF module and antenna. This direct connection bypasses the often limited performance of onboard PCB trace antennas, significantly improving range and signal reliability for IoT sensor nodes, remote telemetry units, and custom wireless devices.

Key Features

  • Provides a direct, low-loss connection between external antennas and module-mounted IPEX1 ports.
  • RP-SMA female connector features a standard 13mm threaded coupling for secure attachment.
  • Flexible RG1.13 coaxial cable minimizes signal attenuation over the 30cm length.
  • Enhances wireless range and reliability by allowing the use of high-gain or directional antennas.
  • Essential for development and deployment of ESP32, ESP8266, nRF24, LoRa, and 4G LTE modules.

Applications

  • Connecting external antennas to Wi-Fi/Bluetooth SoC development boards (ESP32, ESP8266, nRF52840).
  • Extending antenna placement for 4G LTE, NB-IoT, or GNSS modules (SIM7000, SIM7600, Quectel).
  • Improving signal gain and directionality for LoRa/LoRaWAN sensor nodes and gateways.
  • Replacing damaged or suboptimal integrated antennas on commercial wireless devices.
  • Custom RF projects requiring a flexible interface between a chassis-mounted antenna and a compact module.

Frequently Asked Questions

What devices is this RP-SMA to IPEX1 cable compatible with?

This cable is compatible with any wireless module featuring a standard IPEX1 (also called MHF1) antenna connector. This includes popular development boards like ESP32, ESP8266, nRF24L01+, SIM800L, SIM7000 series, and many LoRa modules. The RP-SMA female end connects to most external Wi-Fi, cellular, or GPS antennas that use a standard RP-SMA male plug.

How do I connect this cable to my ESP32 development board?

First, locate the IPEX1 connector on your ESP32 module—it's a tiny, square, surface-mount port. Gently press the IPEX1 end of the cable straight down onto this connector until it clicks into place. Do not pull on the cable to disconnect; instead, use a small tool to gently lift the metal clip on the connector's side. Then, screw your chosen RP-SMA male antenna onto the cable's other end. Ensure the connection is finger-tight to maintain proper impedance and prevent signal loss.

What is the difference between RP-SMA and standard SMA connectors?

RP-SMA (Reverse Polarity SMA) reverses the gender of the inner contact. In an RP-SMA female connector, the center pin has a receptacle (hole), while the standard SMA female has a center pin. This design is common on consumer Wi-Fi equipment to comply with regulations. Using the wrong type (RP-SMA vs. SMA) will prevent a proper electrical connection. Always verify your antenna and device port types before purchasing an adapter or cable to ensure compatibility.
