Description

This RP-SMA female to IPEX1 pigtail cable is a fundamental RF interconnect for wireless system integration. The RP-SMA (Reverse Polarity SMA) female connector mates with standard RP-SMA male antennas, a common configuration on many consumer and IoT access points. The IPEX1 (also known as MHF1 or U.FL) connector is a miniature, push-on interface found on compact Wi-Fi, Bluetooth, 4G LTE, and GNSS modules from Espressif, AI-Thinker, Quectel, and others.

The cable utilizes RG1.13 coaxial cable, a thin and flexible type with a characteristic impedance of 50 ohms, matching standard RF systems. Its 20cm length offers practical flexibility for routing within device enclosures, helping to position an external antenna for optimal signal reception while keeping the module securely mounted. The 13mm threaded section on the RP-SMA connector ensures a mechanically robust and electrically consistent connection, preventing signal degradation from loose fittings.

Key Features

  • Dual-Interface Compatibility: Bridges the gap between external RP-SMA antennas and internal module IPEX1 pads.
  • 50-Ohm Matched Impedance: RG1.13 cable maintains impedance matching for minimal signal reflection and maximum power transfer.
  • Flexible & Durable Build: Thin cable profile allows for easy routing in tight spaces without compromising durability.
  • Secure Threaded Coupling: RP-SMA female connector features a threaded collar for a locked, stable connection to antenna bases.
  • Plug-and-Play Installation: Simple push-on connection for the IPEX1 end and screw-on for the RP-SMA end enables quick setup.

Applications

  • IoT Gateway & Router Antenna Extension: Connect external high-gain antennas to the IPEX1 sockets on embedded Wi-Fi or cellular modules.
  • Wireless Module Development: Facilitate antenna testing and positioning during prototyping with ESP32, ESP8266, nRF52840, or SIMCom modules.
  • Custom Drone & Robotics Builds: Route antenna signals away from electronic noise sources for improved wireless telemetry and control link reliability.
  • Embedded System Enclosures: Run the cable through a chassis wall to mount an external antenna while keeping the wireless module sealed inside.

Frequently Asked Questions

What modules is this IPEX1 (MHF1) connector compatible with?

The IPEX1 connector is compatible with the miniature antenna pads found on a wide range of compact wireless modules. This includes popular Wi-Fi/Bluetooth SoCs like the ESP32, ESP8266, and nRF52840, as well as cellular modules from Quectel (EC25, EG25) and SIMCom (SIM7600, SIM800). It is a standard push-on connector requiring careful vertical pressure to attach and a gentle pull on the cable sheath to detach, avoiding damage to the module's solder pad.

What is the difference between SMA and RP-SMA, and which antenna do I need?

SMA and RP-SMA connectors are mechanically compatible but have reversed gender for the center pin. Standard SMA male has a pin, and SMA female has a socket. RP-SMA reverses this: RP-SMA male has a socket, and RP-SMA female has a pin. This cable has an RP-SMA female connector (with a center pin), so it requires a mating RP-SMA male antenna (with a center socket). Using a standard SMA male antenna (with a pin) would cause a pin-to-pin conflict and damage the connectors. Always verify your device's antenna port type.

What is the typical signal loss for a 20cm RG1.13 cable?

Signal loss, or attenuation, for RG1.13 cable is relatively low for short runs but increases with frequency. At common IoT frequencies like 2.4 GHz, a 20cm length of RG1.13 may introduce approximately 0.5 to 1.2 dB of loss. This is acceptable for most applications, allowing flexible antenna placement. For critical long-range or high-frequency links, consider using a lower-loss cable type like LMR-200 or keeping pigtail lengths as short as practically possible to preserve RF signal strength.
