U.FL (IPEX) to RP-SMA Male Connector Cable - 15cm (Reverse Polarity Plug with Hole)

Specifications

• Connector A: U.FL (IPEX 1 / MHF1) Female

• Connector B: RP-SMA Male (Internal Threads, Center Hole)

• Cable Type: 1.13mm Micro Coaxial

• Impedance: 50 Ohms

• Length: 15 cm

• Frequency Range: DC to 6 GHz

• Insulation: FEP (Fluorinated Ethylene Propylene)

Key Applications & Projects

• Signal Testing: Connect an ESP32 or WiFi module directly to a Spectrum Analyzer or Router port (via adapter if needed).

• Extension: Connect a module to a long RP-SMA Extension cable (which usually has a Female end).

• Packet Injection: Specialized setups where a module needs to act as the antenna source for a Female-connector device.

Virtual Technician & Wiring

• ⚠️ Gender Check:

  • RP-SMA Male (This Cable): Has a Hole. Fits into a jack with a Pin (RP-SMA Female).

  • Standard SMA Male: Has a Pin. Fits into a jack with a Hole (SMA Female).

  • Usage Rule: Check your target device. If it has a PIN sticking out, you need this cable.

Accessories & Parts

What's Included:

Compatible Upgrades:

• Adapter: RP-SMA Female to SMA Male Adapter (to convert it to standard SMA).

• Cable: RP-SMA Extension Cable (Male to Female).

Frequently Asked Questions (FAQ)

1. Will this connect to my WiFi Antenna? NO. Most WiFi antennas have an RP-SMA Male connector (just like this cable). You cannot connect Male to Male. You need the Bulkhead Female version for antennas.

2. Does the RP-SMA connector have a pin or a hole? This is RP-SMA Male, so it has a HOLE in the center.

3. Will this fit a WiFi Router antenna port? YES. WiFi Routers typically have RP-SMA Female ports (Pin + Ext Threads). This cable (Hole + Int Threads) will screw directly onto the router.

4. What is the use case for this? Connecting a module to a router, connecting to an extension cable, or specific RF testing setups.

5. Is the cable 1.13mm? Yes, standard flexible 1.13mm coax.

6. Will this fit M.2 WiFi cards? No, M.2 cards use IPEX 4 (MHF4). This is IPEX 1.

7. Is it compatible with ESP32? Yes, ESP32 modules use IPEX 1.

8. Can I use this for GSM? Only if your GSM equipment uses RP-SMA (rare). GSM usually uses Standard SMA.

9. Is the connector rotating? The nut rotates, the body is fixed.

10. What is the impedance? 50 Ohms.

11. Is it waterproof? No.

12. Can I use this for 5.8GHz? Yes.

13. Is the wire shielded? Yes.

14. Does it come with a nut/washer? No, this is a Plug, not a Bulkhead jack. It does not mount to a panel.

15. Can I extend it? Yes, with an RP-SMA Female to Male extension.

16. Is the contact gold plated? Yes.

17. What if I need to connect to an SMA Female device? You need an adapter (RP-SMA Female to SMA Male).

18. Is this compatible with Raspberry Pi Zero? Yes (if modded with U.FL).

19. Why is it called "Male" if it has a hole? In Reverse Polarity (RP) naming, the gender is reversed. The threads are Male (Internal), but the contact is Female (Hole).

20. Can I use this to connect two modules together? No, unless you have a Female-to-Female coupler.
