Introduction
U.FL, UMCC, IPEX, and MHF Cable Assemblies are micro RF coaxial cable solutions commonly used in small wireless devices. These connections are intended for situations in which space is restricted yet dependable high-frequency signal transmission is required. They are widely used in Wi-Fi, Bluetooth, GPS, LTE, 5G, IoT modules, and embedded RF boards.
U.FL, UMCC, IPEX, and MHF connector are all inter-mateable micro RF connector families made by several manufacturers, despite their varied names.
What Are U.FL, UMCC, IPEX, and MHF Cable Assemblies ?
- A U.FL, UMCC, IPEX, or MHF cable assembly consists of:
- A micro-RF connection installed on a PCB or module.
- A narrow coaxial cable (1.13 mm, 1.37 mm, RG178 or RG316)
- External connectors (SMA, MMCX, MCX, RP-SMA, etc.) or antenna terminating
- These components serve as an interface between small RF modules and external antennas.
Types of U.FL, IPEX, and MHF Cable Assemblies:
1. U.FL to SMA Cable Assembly
