Custom RF Coaxial RF-SMA Female To IPEX1.13 UFL Pigtail Cable

The SMA female to IPEX/U.FL pigtail cable assembly features a 1.13mm diameter coaxial cable with SMA female bulkhead connector on one end and U.FL (IPEX/MHF1) connector on the opposite end. This cable assembly is designed for RF signal transmission between external antenna ports and internal radio modules within compact electronic enclosures. It supports custom cable lengths and connector configurations to match specific mechanical design requirements for commercial procurement and industrial applications.

1.13mm Coaxial Cable Construction and Materials

SMA Female Connector Specifications

The SMA female bulkhead connector is constructed from brass body with gold plating, featuring PTFE dielectric and gold-plated brass center contact. The bulkhead design includes a hexagonal nut for panel mounting, with standard thread dimensions of SMA 50Ω interface. The connector housing provides mechanical stability when mounted through equipment chassis walls.

U.FL (IPEX) Connector and Cable Core

The U.FL (IPEX series 1) connector measures 7.7×7.7×2.5mm, making it suitable for space-constrained PCB layouts. The 1.13mm micro coaxial cable consists of silver-plated copper-clad steel (SPCCS) inner conductor, solid PTFE insulation, silver-plated copper braid shield, and FEP outer jacket. This construction maintains consistent 50Ω impedance along the cable length while preserving flexibility for routing within narrow enclosure spaces.

FAQ

What is the minimum order quantity for custom-length SMA to IPEX cables?

Standard configurations are available starting from sample quantities. Custom length specifications follow standard MOQ requirements set for cable assembly production.

Can this 1.13mm pigtail cable be used for 5.8GHz Wi-Fi applications?

Yes, the cable supports frequency ranges up to 6GHz, which covers 2.4GHz and 5.8GHz ISM bands commonly used in Wi-Fi and other short-range wireless systems.

Are the connectors pre-attached or does soldering work need to be done on site?

All connectors are factory-terminated onto the cable. Each assembly undergoes continuity testing before shipment, so no additional soldering is required during installation.

What is the typical insertion loss of this cable assembly?

Insertion loss varies by cable length and frequency. For a 100mm cable at 2.4GHz, typical insertion loss measures approximately 0.3dB. Loss values increase with both frequency and cable length.
