The PCM-SHM-0081 SMA to U.FL IPEX 4 RG1.13 Coaxial Cable Assembly is designed for ultra-compact IoT modules, WLAN devices, and RF communication systems requiring minimal cable diameter and flexible routing. Built in our own RF cable assembly factory, each cable is manufactured with reliable materials and undergoes strict quality inspection.
This assembly uses a gold-plated 3U" SMA female bulkhead connector, supporting a 6.4mm recommended mounting hole. The opposite end features the IPEX 4 micro coax connector, which is widely used in high-density RF layouts and next-generation IoT boards. The RG1.13 coaxial cable provides excellent flexibility while maintaining stable 50-ohm impedance.

Difference Between IPEX 1 and IPEX 4
Although both IPEX 1 and IPEX 4 belong to the same micro-coax connector family, they differ in size, retention strength, and application compatibility.
| Feature | IPEX 1 (U.FL / MHF1) | IPEX 4 (MHF4) |
|---|---|---|
| Connector Size | Larger | Smaller (Miniature) |
| Mating Compatibility | Not compatible with IPEX4 | Not compatible with IPEX1 |
| Typical Use | WiFi modules, early IoT boards | Ultra-compact IoT, LTE, 4G/5G modules |
| PCB Footprint | Larger landing pad | Significantly smaller landing pad |
IPEX4 is the newer, smaller generation, ideal for space-limited devices such as:
- Miniature IoT boards
- Cellular modules
- Wearable electronics
This makes PCM-SHM-0081 especially suitable for next-generation RF products.
Applications
- IoT terminal devices
- 4G/5G modules
- Compact WiFi platforms
- Embedded RF systems
- Wearable and portable electronics
