Description

This RP-SMA Female to IPEX4 connector cable is a fundamental RF interconnect for IoT developers and system integrators. It bridges the gap between a standard reverse-polarity SMA antenna port and the miniature IPEX4 (U.FL) connectors found on compact wireless modules like ESP32, nRF52, Quectel cellular modems, and LoRa transceivers.

The 30cm RG0.81 coaxial cable provides sufficient length for flexible installation within device enclosures while maintaining signal integrity. Its 50-ohm impedance is matched to standard RF systems, minimizing VSWR and insertion loss for reliable wireless performance in 2G/3G/4G/5G, Wi-Fi, Bluetooth, GPS, and LPWAN applications.

Key Features

  • Direct interface conversion from panel-mount RP-SMA to board-level IPEX4 (U.FL).
  • RG0.81 coaxial cable with 50-ohm characteristic impedance for optimal RF performance.
  • 30cm length offers installation flexibility for internal antenna routing.
  • IPEX4 connector locks securely onto module pads for stable RF connection.
  • Enables use of external high-gain antennas with compact wireless SoCs and modules.
  • Essential for prototyping, testing, and final product integration of wireless devices.

Applications

  • Connecting external antennas to ESP32, ESP8266, or Raspberry Pi Wi-Fi/BT modules.
  • Providing an antenna port for Quectel, SIMCom, or Telit 4G LTE cellular modems in custom enclosures.
  • Routing GNSS/GPS antenna signals to compact tracking devices.
  • Extending antenna placement for LoRa/LoRaWAN node prototypes for improved range.
  • General-purpose RF interconnection in IoT gateway and router designs.

Frequently Asked Questions

What modules is this RP-SMA to IPEX4 cable compatible with?

This cable is compatible with any wireless module featuring an IPEX4 (U.FL) antenna pad. This includes common Wi-Fi/Bluetooth SoCs like the ESP32-S3, ESP32-C6, and nRF52840, as well as cellular modules from Quectel (EG25-G, EC25) and SIMCom (SIM7600, SIM7000). It connects these modules to an external antenna with an RP-SMA male connector, typical for many panel-mount antenna setups.

How do I securely connect the IPEX4 connector to my module?

Align the IPEX4 connector carefully with the gold-plated pad on your wireless module. The connector has a small center pin and an outer shield. Apply gentle, even pressure straight down until you hear or feel a faint click, indicating the internal latch has engaged. To disconnect, gently pull the black plastic housing straight up—do not pull on the cable. Misalignment or twisting can damage the fragile pins on the module's PCB.

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

SMA and RP-SMA (Reverse Polarity SMA) connectors have reversed gender for the center pin. A standard SMA male has a pin, while the female has a socket. In RP-SMA, this is reversed: the male has a socket, and the female has a pin. This cable has an RP-SMA Female connector (with a center pin), designed to mate with an RP-SMA Male connector (with a center socket), commonly found on many Wi-Fi routers and external antennas to comply with regulatory standards.
